8 Statebirds in Southwestern Louisiana, Including Some Nice Rarities – February 2017




Back in January I took a successful 1-day statebirding trip to southwestern LA, adding 6 new birds to my list (summarized in an earlier blog post).  While doing research for that trip I noticed quite a number of reliable rarities and other more common targets being seen in the southeastern part of the state.  Certainly too far away to try for during my brief January trip.  But when a rare business trip to New Orleans and Baton Rouge came up in February I was already excited about those possibilities before even starting on my local research.


Of course my first step was to set up a Needs Alert, focusing my attention not only on Baton Rouge and New Orleans but also on the north side of Lake Ponchartrain.  Several apparently reliable rarities stood out like 2 Western and 1 Couch’s Kingbirds at Fontainebleau State Park, and several Ash-throated Flycatchers and older sightings of a Brown-crested Flycatcher at Bayou Sauvage NWR.  There were also numerous reports of Purple Finches and Woodcocks throughout the area, though I couldn’t find what seemed to be reliable sites for these targets.  And then there were the ever-present, but difficult to spot, Brown Boobies at the Lake Ponchartrain causeway.  On the waterfowl front, I needed Redhead and Common Goldeneye, but the few sightings in the area were now pretty old.

Then there are the hummingbirds.  LA is well-known for its nice collection of western hummingbirds that winter at feeding stations.  Although I already had 6 hummingbird species on my LA state list, the eBird report included 2 more that I needed – Calliope at 4 locations, and 1 banded Allen’s.  Another good resource for information on LA’s wintering hummingbirds is HUMNET which provides a detailed compilation of species by parish.  Although these sources provided general locations for the birds, I still needed specific addresses, and most importantly invitations from the homeowners to be able to bird at these feeders.  I reached out to Erik Johnson who compiles HUMNET to see if he could assist in my searches.  Erik was able to get me access to 3 of the feeders with Calliopes, and connected me with the birder that had the Allen’s.  Unfortunately I found out that the Allen’s had moved on, so that one was off my target list.  Erik also gave me tips for a site for Redheads, and a spot for both Woodcocks and Henslow’s Sparrows.  The Henslow’s hadn’t even been on my radar screen so that was a nice additional target.  But the observations Erik mentioned were from Christmas Counts, so they were now getting quite old.

Next I reached out to my LA birding friend Marty Guidry.  Although he couldn’t bird with me on this trip, he had tips for a couple spots around Baton Rouge, including a feeding station with both Calliope Hummingbird and Purple Finch.  And if I struck out on the Finch there, Marty had them at his feeder.  Marty also checked on an older Goldeneye sighting in the area, and confirmed that that bird had moved on, saving me time to do a search for the bird.

Chasing after these targets efficiently would be important on this trip, because as usual I had limited time and lots of potential birds to chase after.  I would be free a couple hours before work and after work on the first day of the trip.  And given how many targets I had, I decided to take the afternoon off on the second day.  My plan was to bird near Baton Rouge in the morning of Day 1 to try for the Calliope, Purple Finch and Redheads.  Then late in the day near Covington I would try for Woodcock, Henslow’s and Redheads again (if necessary).  Then in the afternoon of Day 2 I would try for the 4 flycatcher rarities at Fountainbleau SP and Bayou Sauvage NWR.  And depending on my earlier luck with Calliope I could either end the day with another Calliope try, or take a trip on the causeway for the Boobies.  That itinerary would give me 10 targets to try for. 

But there was one additional concern to be aware of – mid-February in LA isn’t exactly very winter-like.  For instance with 80 degree temperatures the week before I arrived, I had heard that the Purple Finches were now more likely to be feeding on tree buds rather than at feeders.  And the most recent flycatcher posts were all now at least 2 weeks old.  Plus of course Christmas Count reports were 45 days old.  So I worried that many of the “wintering” targets might have already started to head north (or west!).  So I tempered my enthusiasm and hoped for maybe 4 or 5 new statebirds for the trip.

Day 1 – Early AM

At dawn I was pulling into Donna Dittmann’s and Steve Cardiff’s property outside Baton Rouge.  Marty had told me that they had purchased the property years ago and had been managing it to for wildlife, and of course for birds, ever since.  Donna took me on a quick tour which featured dozens of hummingbird feeders scattered throughout their amazing “yard”.  She described how each hummingbird has a wintering territory, and pointed out which feeder was preferred by each of their hummingbirds.  Along the way we spotted a female Ruby-throat, a male Black-chinned, a couple Rufous, and the first of 3 Buff-bellieds.  Then we got to the preferred feeders of their female Calliope and soon heard the chip notes that Donna recognized as the Calliope.  A few second later there was the target hummingbird, looking downright tiny compared to the other species (LA statebird #1).  Not only was it nice to check that one off, but it also meant I would not have to spend time looking for it at other feeders the next day.  LA is my fifth state for Calliope outside its normal breeding and migration ranges.


We then headed back to the house to try for the Purple Finches.  Although they had been seen at the seed feeders the day before, they were becoming less regular as spring approached.  As I stood out on the deck the feeders had a pretty constant stream of visitors, including Cowbirds, Cardinals, House Finches, White-throated Sparrows, and a lone Red-breasted Nuthatch.  But no Purple Finches, nor Goldfinches with which they were frequently associating.  Then I heard a short warbling song coming from high above me in the trees overhead – a singing Purple Finch (LA statebird #2).  I heard it sing 2 more times, then the bird gave several of its “pik” notes, though I never saw it.  Good thing I know its song and call.  I just need this species in a couple more southeastern states in its wintering range.
 

I waited a bit longer to try to get a visual on the Finch but with no luck.  So with enough time for one more brief stop before work I thanked Donna and Steve and was back on the road.  The next stop was a speculative one for Redhead – the Denham Springs wastewater treatment plant where one lone report 3 weeks earlier featured 20 Redheads.  But a quick look from the road yielded only a small flock of Shovelers.  Unfortunately there was no access to the much more reliable spot for Redheads in the area - nearby LSU Aquaculture Research Station (which also featured an Ash-throated Flycatcher).  So striking out here left me with just 1 more iffy spot for Redheads I would try to visit that evening.

Day 1 - Evening

I got out of work right on time and soon was on my way east to the Lake Ramsay WMA.  After Erik’s tip for Henslow’s Sparrows there, I did some eBird research and found quite a number of posts with up to 21 Henslow’s reported, though there were no reports in the last 2 weeks.  I had pretty specific directions to search in one area of wet savannah, and even more specific suggestions to especially bird areas with scattered small brush rather than just open grasslands.  But it would be difficult to find these secretive birds on my own.  That is if they were still there in the first place.

With duck boots on I was ready to walk through the wet grasslands.  But on the first 100 yards of my walk the ground was actually pretty dry, so I wondered if the area was still wet enough to attract the Henslow’s.  Though calling Brown-headed Nuthatches were a nice consolation.  Then I finally reached some wetter areas, including remains of last year’s pitcher plants among the grasses.  But I was still in open savannah, so I headed to an area with some scattered bushes as recommended.  And as soon as I got to that patch I flushed a large dark sparrow.  It landed in the bush and just sat there – a most cooperative Henslow’s Sparrow (LA statebird #3).  I don’t know which was more beautiful – the greenish color to the face or the rusty patterned back and scapulars.  I can’t remember having better views of a Henslow’s.  My statebird map for Henslow’s is pretty spotty for this bird, where LA is only my third state in its wintering range (hmm – I need it in TX in winter…).


Later I would flush a second Henslow’s though this one wasn’t nearly as cooperative.  The next target here was Woodcock that Erik had as a flyby at dawn on the Christmas Count.  I figured a flyby at dusk was just as likely.  And now that it was later in the year perhaps they could be calling, assuming they all hadn’t headed north by now.  But it was still more than an hour before sunset, so I had some time to kill.  I then though about the spot Erik had mentioned where Redheads had been reported on a Christmas Count – a small man-made lake along Ochsner Blvd in Covington.  It was about 20 minutes away so I had just enough time for a short stop there before heading back to try for the Woodcocks at dusk.  But with no Redhead eBird reports from this spot at all, I wasn’t very optimistic.

I arrived at the lake on Ochsner Blvd and unfortunately found that it was fenced off.  As a result I could only find one limited viewing spot looking through the fence, and worse yet I was looking right into the setting sun.  I set up the scope and scanned the small portion of the lake without the sun glare, and only found a couple Pied-billed Grebes.  This was turning out to be a waste of time and I started to wonder why I didn’t just continue to bird the Lake Ramsey area.  Then I noticed some waterfowl in the sun glare.  I did my best to look at them in the scope and thought I was seeing red color on the heads of some of the birds, but couldn’t be sure.  Then a few birds swam to the left out of the brightest sun and they were indeed Redheads.  I eventually counted an amazing 46 birds (LA statebird #4).  Boy was I lucky – if they had stayed in the part of the lake in the sun glare I wouldn’t have noticed them.  I only need Redhead in 3 more states to completely fill in my statebird map for this species.


I made my way back to Lake Ramsay WMA and stayed till dark but had no luck either seeing or hearing Woodcocks.  On a whim I even tried some tape for Whip-poor-will and Chuck-will’s-widow while waiting in what seemed like good habitat for these wintering and/or migrant birds, but to no avail.  Though I did have numerous Sedge Wrens that serenaded me during my wait.

Day 2 – Afternoon

My first stop after work was the Fontainebleau SP where 2 Western Kingbirds and 1 Couch’s Kingbird had spent much of the winter.  After poring through all the eBird reports I was able to piece together some pretty specific information on their locations – most often seen near the group cabins and sometimes at the nearby individual cabins.  And although all 3 birds were often seen together, the Westerns seemed to be the easiest ones to find.  One last important tip was that they often responded to playback.  So although I was optimistic, the last report (positive or negative) was 2 weeks earlier.  In fact, recent posts on the listserve from the park focused on King Rails and not Kingbirds.

After arriving at the park I drove right to the cabins, and first took a slow walk around the entire area where the Kingbirds had been reported.  I decided to not play any tape at first, hoping to find them without playback.  It was a pretty birdy area with many Yellow-rumps flitting about, and I found a perched Shrike and a couple perched Mockingbirds, but no Kingbirds.  With no success on my first loop through the area I started to play tape – both of Couch’s and Western.  I had passed through almost all the area again but still had no luck.  Then at the edge of a clearing I spotted a larger bird fly up from the ground to perch in a tree what showed quite a bit of yellow.  My first thought was it was a Flicker “anting”, but when I put it in the binocs I realized it was one of the Kingbirds.  But which one?  It cooperatively perched nearby and showed a yellow (not gray) chest.  With a bit more time I could see the tail was rusty brown and not black, and lacked white outer tail feathers.  It was the Couch’s Kingbird .

Or was it?  Once I started to hear it call it didn’t sound anything like the taped calls I had been playing.  In fact the calls were more like a Western than a Couch’s.  Then I heard it sing and the song was nothing like the tape.  Then I looked down at my BirdTunes app and realized all along I had been playing Cassin’s Kingbird calls instead of Couch’s Kingbird.  When I started playing the calls of the correct Kingbird species the bird came right in to investigate.  And the song was a perfect match.  So I could finally count it as a Couch’s Kingbird and LA statebird #5 – only my second state for this species in addition to TX.

The bird was most cooperative, in view or calling for most of the rest of my 3 hour visit to the site.  I got this picture holding my phone up to my binocs.


Now I needed to find what had been the more reliable Western Kingbirds.  But despite 2 more hours of walking through the area, and playing the correct Kingbird calls, I never found them.  Although I wanted to stay longer, I still needed to bird Bayou Sauvage, so I headed out of the park assuming that the Westerns had moved on.  As I drove away I was disappointed to have missed the Westerns, but I was happy to have found the rarer of the 2 species.  [As I write this post, since my visit there the Couch’s has been reported again on eBird but not the Westerns, so likely the latter have indeed left their wintering site.] 

The key target birds at Bayou Sauvage NWR were up to 3 Ash-throated Flycatchers that had been seen in the area since November.  There had also been a Brown-crested Flycatcher at the refuge, also with sightings going back to November, but the last sighting of this bird was 45 days ago.  Then again, a more recent eBird post suggested that the observer may well have seen the Brown-crested associating with an Ash-throated.  In any case it was an additional bird to watch for.

The next step was to figure out the locations of the past sightings of these birds.  One might think that with all the many posts on eBird it would be easy to figure out microdirections for the locations of these birds.  But most sightings had few if any details as to location (remember eBird asks for ID details on rarities and not info on the locations of these birds).  In fact, many of the posts were associated with the general hotspot for the entire Bayou Sauvage NWR, which covers a very large area.  And some mentioned locations that might be obvious if you had birded the area before, but not specific enough to birders who were new to this spot (e.g., “across from the hog trap”).  I finally figured out that most sightings were along Recovery Road, but then couldn’t find this road on GoogleMaps.  Luckily it was shown on the pdf map of the refuge that I found online, so that was a start.  And several mentioned the southwest corner of the landfill, and some mentioned south of the railroad tracks.  These features also showed up on the refuge map – the tracks were about ½ mile south of US 90, and the landfill was another ½ mile south, all along Recovery Road.  I finally felt like I knew where to go.

After a drive around the eastern side of Lake Ponchartrain I arrived at the Bayou Sauvage NWR and parked at the north end of Recovery Road.  This turned out to be quite a “seedy” spot, with a number of present and former industrial activities in the area.  In fact, Recovery Road was a gated road with trash dumped on both sides.  And now my research was starting to make sense – what used to be Recovery Road dead-ended at what was likely a former industrial landfill built in the middle of a large wetlands.  Certainly not a spot anyone would want to live, but the kind of area that frequently provides some good birding habitat.  (We’ve all birded at spots like these…) 

I started my walk south along Recovery Road and started to get my bearings.  A canal ran along the west side of the road, likely the source of soil used to build up the land to make the road itself.  And in between the road and canal was a line of low trees and brush.  Most of the rest of the area was marsh and other wetlands.  The “woodlands” north of the railroad tracks was full of Yellow-rumps, and although I wanted to stop to check them out, all the flycatcher sightings had apparently been south of the tracks, so I kept going.  After waiting for a train to pass by, I crossed the tracks and started to bird the brushy habitat.  Again I ran into flocks of Yellow-rumps, and soon started to find a number of Phoebes, but couldn’t turn any of them into a Myiarchus of any species.

I continued walking slowly south, birding along the way, and soon reached what looked to be the landfill to the east.  (I also found the hog trap nearby.)  Although the road continued farther south, all the sightings seemed to be no farther south than the landfill, so I turned around here and slowly starting walking back to the north.  At this point I heard a series of single notes off to the east toward the landfill that I couldn’t place - sort of sounded like “preep”.  Although I wanted to turn it into one of my targets, they didn’t really match calls of either the Ash-throated or the Brown-crested.  In any case the bird soon stopped calling, so I continued my walk north.  Now I was playing tape of both species, but got no responses.  By the time I reached the tracks I had seen several Phoebes, but nothing new. 

I made this round-trip circuit 2 more times but still found none of my targets.  Though one more time I heard the “preep” calls coming from the landfill in the distance.  And after 2 hours of trying, I was starting to wonder if these birds had moved on, just like the Western Kingbirds at my earlier stop.  Afterall the most recent Ash-throated report was now 11 days old, so maybe I was too late. 

I was now on Recovery Road near the southwest corner of the landfill, and was about to give up.  But then on a whim I thought about trying at the actual southwest corner of the landfill, not on the road near that spot.  The landfill was only 50 yards to the east, but it was worth the try.  I walked up the berm to the edge of the landfill and played Ash-throated calls.  Instantly I started to hear the same “preep” calls I heard earlier.  And just then a flycatcher flew in – it was a Myiarchus.  My first gut feel was that it was a big bird – too big to be the diminutive Ash-throated.  And then the bill seemed too big.  I started to play Brown-crested calls and the bird became very agitated.  It continued to call, and although these calls weren’t a perfect match, they were certainly closer to Brown-crested than Ash-throated.  The bird occasionally came out into the open, and I tried to get phonescoped pictures of the bird, but with limited success.  At one point when the bird out of view I quickly checked my photos on my phone and looked at this photo that I initially thought was miserably out of focus. 


But then with a closer look I realized that I had gotten a good photograph of the underside of the tail – the tip is rufous red with only dark corners.  That confirms the ID as a Brown-crested.  I also was able to get this "video" of the bird calling.


That was my 6th LA statebird of the trip; LA is my 5th state for this typically southwestern species.


The bird then flew to the trees along the road, and slowly made its way north, calling almost non-stop.  After 15 minutes with the bird, I parted ways and started my walk back to the car.  I looked back and could hear the bird still calling in the distance – the same sounds I heard earlier from the landfill.  I smiled as I realized that I had actually been hearing this bird all along.  And just then I noticed a small Dove fly from the landfill over the road and out of site to the west.  It had red wing-linings making it a Ground or Inca Dove, and given the short tail, it had to be a Ground Dove.  Although I didn’t think much of it at first, I realized that I might need this one for LA.  Sure enough it was new for my LA statelist, my 7th of the trip, though not even on my radar screen as a possible target.  After the fact I checked eBird and noticed that there had been a few Ground Doves reported from the landfill area – one I had overlooked in my research.  LA is my 9th state for this species, and although a rare bird in LA, not nearly as rare as the one I recently saw in MA.


As I continued back north up Recovery Road toward my car I realized that, like my experience with the Kingbirds earlier, I had found the rarer of the two targets, but not the comparatively more common species.  A disappointment, but still nice to get the rarer one.  I was now nearing the railroad tracks and spotted a flycatcher up ahead perched near the road.  I initially took a cavalier attitude toward it, and assumed it was one of the many Phoebes I had spotted in that area.  But I put my binoculars on it and it was an Ash-throated Flycatcher (LA statebird #8).  I had been in this area several times over the last 3 hours without spotting it - wonder where it had been.  LA is a nice addition to my statebird map for this species, which includes 5 New England states where I’ve also seen it as a rarity.
 

Ash-throated was my 7th flycatcher species I had seen in 2 trips to LA this winter – Eastern Phoebe, Say’s Phoebe, Scissor-tailed, Vermillion, Couch’s Kingbird, Brown-crested, and Ash-throated.  That’s quite a nice collection of rarities more typically seen in the southwest.  And also a nice way to end my stop at Bayou Sauvage.  To think just 30 minutes earlier I was ready to leave the area without any of my targets.

With a little time to spare, and having checked off the Calliope Hummingbird the day before, I decided to make a try for the Brown Boobies on the Lake Ponchartrain causeway.  Booby sightings along the causeway go back to 2015, with up to 35 reported on eBird.  That all makes it sound like they would be easy to find.  But - these birds roost under the bridge, and principally only under one short stretch of the bridge.  So when looking for them by car, you have to hope that one or more happens to be flying by along the bridge close enough to ID while you’re driving by at 60+ mph.  And by the way, there is no stopping on the bridge either.  As a result, not surprisingly the 35 birds were reported from a boat.  I made 3 unsuccessful round-trip attempts for the Boobies last year, so I knew the drill.  Alas this one was no different.  Best I could find was a few Pelicans, Gulls, and Terns.  It’s frustrating to think that the Boobies are likely no more than 20 feet below you but invisible as you pass by overhead.  At least the toll is only $3.

Despite the Booby frustration I was very happy to have added 8 new birds to my LA statelist, 5 of which were rarities requiring documentation in eBird.  That brings my LA statelist to 270 – a nice respectable total for a northeasterner.
