Thirteen Statebirds in Nebraska – “Reportable Plus 15”, January 2016



My annual spring birding trip in 2009 included multiple days in western NE, where with the advice of several local birders, I increased my statelist from a miniscule 124 all the way up to 213.  With an ABA reportable threshold of 225 at the time, I needed another couple short trips to the western end of the state in 2010 to reach and then exceed the threshold, adding 19 more to get to a respectable 232, or 7 over the old ABA threshold. 

The ABA used to calculate the state thresholds as half of the total number of species seen in the state.  Although the thresholds are no longer published by the ABA, with a little web research you can generally find the latest state totals, and calculate a new threshold by dividing that number by 2.  For NE, the statelist as of December 2015 had increased to 461, resulting in a newly calculated threshold of 230.5.  So now my total was only 1.5 over the present threshold, meaning I could be below threshold with the addition of just 4 more species (or splits) in the state.  NE is a good example of why, instead of just aiming to be above the old ABA threshold, I have come up with a goal of being at least 15 over that total in any given state - “reportable plus 15” as I call it.  That should give me a comfortable cushion to stay above threshold for quite a number of years to come.  And to give me that cushion in NE, I needed to get back there to add some more statebirds! 

I don’t get to the region very often, so when a January business trip to Denver came up I started thinking about whether adding a couple vacation days for some western NE birding could yield a sufficient number of statebirds to make it worthwhile.  The closest I’ve been to winter birding in NE was a trip to the state in early November 2010, so I had a pretty long list of at least remotely possible target birds.  But there was a reason why I haven’t done mid-winter birding in NE or most other states in the region - mid-winter weather in the plains can be cold, windy, or snowy, making traveling and even birding difficult if not impossible.  Of course I would have to make my plane arrangements well before I could get any local weather forecasts.  But given that I was only barely above threshold, and that there were numerous possible targets, I decided to add 2 vacation days to the Denver trip and cross my fingers for at least 1 good day of weather.  Plus the Ogallala area with Lake McConaughy and Lake Ogallala was one of my favorite birding spots anywhere across the country, so it would be great to get back there.  I figured if I could get 4 or 5 new birds for NE it would be a successful trip.

Now it was time to do the local research.  The first thing I did was to set up a Needs Alert on eBird, which showed that many of my targets were being seen in the state.  However, the vast majority were from the eastern portions of NE.  Then I turned to the NE listserve which had a fair number of posts from the western part of the state, including sightings of a few of my targets.  Then came posts from the Lake McConaughy and North Platte Christmas Counts where many of my targets were spotted, plus several rarities not even on my target list.  I contacted the count compilers and got great local information or many of their sightings.  But despite initial enthusiasm I realized my trip would be 3-5 weeks after the counts, so these would be very old sightings by the time I got to the area. 

As the trip neared there were few posts from western NE and even fewer possible targets reported.  I also reached out to Kathy DeLara, a birder in Scottsbluff who I had birded with in 2009, and she mentioned that there were reliable sightings of only 2 of my possible targets in her area.  Now I was worried that I might not even get the 4 or 5 new statebirds I was hoping for.  But then the week before my trip there was a listserve post from NE birder Joel Jorgensen who spent a couple days in the Lake McConaughy/Lake Ogallala area.  He found 10 of my targets - now I was pumped!  With microdirections from Joel, I now had a possible target list of 18 birds, though realistically I hoped for about 7 of these as new NE statebirds.  And then I realized I would only need 1 more to reach the “reportable plus 15” goal.  Plus the weather was looking warm and dry for the trip.  So everything was falling into place.

My plan was to leave Denver when work was done around noon on Day 1, and then take a 3-hour drive to Ogallala.  I would bird a few hours in the area till dusk that day, and then again till mid-day on Day 2.  Then I would head east to North Platte and bird there in the afternoon and a few hours in the morning on Day 3.  The last set of stops would be near Scottsbluff, on the way back to Denver that night.  A busy itinerary, but that would give me stops at many good birding spots in the area.

Day 1

Work was over right at noon, so everything was right on schedule as I left Denver.  During the long ride to Ogallala I thought through my target list and realized that if everything fell into place there was a remote chance that I could get 8 or more of my targets even in my short time available that evening.  I had lots of optimism when I arrived in the town of Ogallala, and headed right to a feeder where a White-winged Dove and been seen for much of the winter.  As I arrived the homeowners greeted me at the door and took me into the back yard where the Dove was sleeping on its favorite perch (statebird #1).  NE is at least the 6th state where I’ve seen this species which is prone to vagrancy as a rarity (see my statebird map below).


I spent a few minutes talking with the very friendly homeowners, but then was off to Lake Ogallala just northeast of town.  Lake Ogallala is a small lake just below the enormous Lake McConaughy.  Despite its small size it seems to attract many more waterfowl than the larger lake, including quite a number of rarities for this inland location.  For instance on my November 2010 visit I found all 3 Scoters on Ogallala.  And it is also well-known for quite a diversity of gulls in the winter, especially attracted to fish coming through the tailrace where water is discharged from McConaughy into Ogallala (I had a Lesser Black-back and a California there in November 2010). 

I pulled into the park around Lake Ogallala and went right to the tailrace to take a quick look.  There were only a few Ring-billed and Herring Gulls at the tailrace so I started a quick scan of the lake.  The lake was about half frozen over, but the open water was absolutely full of diving ducks, mostly Scaup and Goldeneye.  And since I needed Common Goldeneye for my NE list, that one was a quick addition (#2).  A large flock of Canada Geese were swimming near the back of the lake, along with even more divers, and 6 Trumpeter Swans (#3).  NE was my 15th state for this expanding re-introduced species which wasn’t even on my target list when I was last in NE in 2009-2010.


Next I started scoping through the divers, first concentrating on the Scaup in search of several Greaters that had been reported.  It didn’t take long before I had several pairs of Greaters mixed in with the more numerous Lessers (#4).  In fact I think there were a fair number of Greaters on the lake.  I only need Greater Scaup in 7 more states for a sweep of the mainland states.


And then my attention was drawn to a Goldeneye that was swimming all by itself.  It was a female and a bit smaller than the other Goldeneyes.  Although it was diving a lot, I kept thinking I was seeing an all-pale bill.  Eventually it stayed on the surface long enough for me to get a good look at its head – it indeed had an all yellow bill and a forward-sloping head shape.  It was a female Barrow’s Goldeneye (#5).  Although a male Barrow’s had been reported from the tailrace recently, no one had reported a female.  NE was my second central US state to find this species as a rarity, not to mention seeing it in 7 states in the northeast.


Next I spent some time scanning through the Canada Geese in hopes of finding one of their rarer cousins.  The flock numbered at least a thousand, with about half swimming in the open and the others standing and sleeping on the banks and in the marshes.  But with such a large flock many birds were frequently hidden behind others, so it took more than just a quick scan to see all the birds.  At one point I noticed a glimpse of pink among the otherwise brown birds on the shore – it was the bill of a White-fronted Goose (#6).  Eventually it walked out from behind the Canadas affording good looks - the second rarity I found that wasn’t recently reported at Lake Ogallala.  It was turning out to be quite a start to the trip, and there was more to come. 

I changed angles to look at the northern part of the lake near the edge of the ice.  Waterfowl were less numerous here, and featured a large flock of Common Mergansers.  Then I spotted a male White-winged Scoter which had been reported recently.  On another scan I noticed a pair of Long-tailed Ducks (#7) swimming right at the ice edge – only 1 had been reported there recently.  NE is my 4th inland state for this typically coastal species.


Having completed a pretty thorough review of the waterfowl finding all my targets and then some, I turned my attention back to the tailrace to look through the gulls.  Recent reports had included a couple Lesser Black-backs and a 3rd-year Glaucous.  Although there were only about 25 gulls there one of the first birds I found was a Lesser, and then a second Lesser appeared – both were 3rd-year birds pretty well into adult plumage except for a bit of a black tail band.  And then I picked out a 1st-year California.  Nice rarities but not new statebirds.

Then I noticed a gull fly overhead that looked pure white below.  My first thought was that this must be the Glaucous reported a week earlier.  But then I realized it was way too small – not too much larger than the Ring-bills.  From above the mantle was the color of an adult gull, and the wings appeared all white, except for only a hint of darker coloration in the primaries (although it took me a long time before I saw any dark feathering at all in the primaries).  The tail was mostly white with a narrow band only slightly darker than the tail near the tip, though there was a thin band of white at the very tip.  The bill was yellow except for a ring, very much like Ring-billed.  Was this a very rare Iceland or the much more expected Thayer’s?  I would think that by the time a Thayer’s is in 3rd year plumage it would have some noticeable darkness in the primaries as it approached the adult plumage that typically has quite dark wing tips.  As I wrote in eBird – “If I were back on the MA coast I would quickly call this an Iceland, bit this is NE...”  I traded e-mails with Joel Jorgensen who had tentatively reported the Glaucous the previous week, and it turned out that this was the same bird he had seen briefly and photographed.  One of Joel’s photos is provided below.



And here’s one of my photos taken with just my iPhone with no magnification.


After further review, and sending Joel’s photos to some gull experts, we agreed that this was a rare Iceland Gull.  That gave me 5 species of gulls even though there were just 25-30 birds present.  NE is my 4th state for Iceland Gull away from the northeast.


And that was statebird #8 for the trip – bringing my NE statelist to 240 – reportable plus 15.  My 36th state reaching that goal (I have 45 states over the ABA threshold).  And amazingly I was just a couple hours into my planned 2+ day trip.

I spent the next 30 minutes at the tailrace hoping for more gulls to arrive, but just kept seeing the same Iceland and Lessers.  Certainly can’t complain about that!  At one point the locks were opened and quite a bit of water was released through the tailrace.  Goldeneyes and Mergansers starting flying in from the lake looking for a quick meal.  Interestingly, almost all were males, including the male Barrow’s reported earlier.  Along with at least a dozen Bald Eagles of various ages, it made for quite a spectacle.

It was now close to sunset and time to head to fields just outside the park where Joel had reported Short-eared Owls the previous week.  With some time to spare before dusk I drove along the road and found what I hoped would be the best spot to be able to scan the fields for these nocturnal birds.  I set up my scope on the shoulder of the road and prepared to wait for dusk.  Just then I noticed a “bump” on a distant fencepost in the middle of the field.  I put my scope on it and it was a Short-eared Owl perched on the post (#9).  As I was looking at it another Short-ear flew through my scope field.  I then scanned with binoculars and saw at least 3 birds flying about, with all this activity starting at least 30 minutes before dusk.  At one point a bird flew to within 30 feet of me seemingly checking me out.  I even heard one of the birds “bark”.  That was by far one of my best experiences with Short-ears.  Given the challenges of finding these birds at dusk, my statebird map is really spotty, having seen this species in just 21 states though it can be seen throughout almost the entire country.


What an amazing start to the trip!  In just 2 hours of birding I had added 9 statebirds, already exceeding my expected total for 2 days of birding.  As a result, I no longer needed to make a trip to Scottsbluff since I had already seen the 2 possible targets there (Common Goldeneye and White-front).  And in fact, since my list of remaining targets was so short, I decided to cut out the last birding day altogether.

Day 2

I started at first light at the tailrace at Lake Ogallala hoping for additional gulls.  But with the exception of several Bald Eagles, the tailrace was very quiet.  That is except for the noise of the strong northerly winds that had surprisingly picked up overnight.  I found a spot somewhat out of the wind, and decided to wait it out a bit longer.  At one point I noticed a pair of birds fighting in mid-air over the hills to the south.  One was a Flicker and the other was an Accipter that wasn’t too much larger.  After the two birds separated, I was able to identify the small Accipter as a Sharp-shinned Hawk with its fluttery flight and small head/neck (statebird #10).  That’s another species that I only need in a few more states to fill in the rest of my statebird map.


I eventually gave up on the tailrace, and turned my attention to the waterfowl on the reservoir.  The flock seemed relatively unchanged from yesterday, so I was about to move on when I noticed a lone goose flying into the goose flock – it was a Snow Goose (#11).  I later re-found the White-front in the flock as well.  It’s not surprising that 5 of the 9 remaining states where I still need Snow Goose are across the northern tier where I’ve done little if any birding outside of summer months.


With one last stop on the lake to check out a small group of gulls I found one of yesterday’s Lesser Black-backs and an adult Thayer’s – my 6th gull species even though I saw less than 100 gulls in total over 2 days.

Next I headed up to Lake McConaughy to try for some waterfowl.  Unfortunately I was looking right into the wind, making viewing difficult.  Regardless, I didn’t see a single bird on the water.  Though I did refind yesterday’s Iceland Gull hovering overhead in the updrafts off the dam.

Then it was over to Keystone/Roscoe Road east of Lake Ogallala.  The key target here was a flock of Redpolls that Joel Jorgensen had had at a small cattle ranch there the week before.  As soon as I pulled up to the spot I could hear a lot of Goldfinch chatter, so I moved in closer to the flock to check for other finches.  I estimated there were at least 200 Goldfinches along with a small number of Siskins feeding in the weedy vegetation, but rarely were more than a dozen in view at any time.  Then I heard a couple brief call notes that could have been a Redpoll.  A few minutes later a lone bird flew over my head giving distinct chit-chit calls of the Redpoll (#12).  NE was only my 14th state for this species – another example of missing a rather widespread species by only doing limited mid-winter birding across the country.

 

My last stop in the area was to bird along the canal below Lake Ogallala in search of Rusty Blackbirds seen by Joel.  Unfortunately I found no blackbirds at all, but a nice consolation was finding a field with about 50 Horned Larks and 1 Lapland Longspur (though alas no Snow Buntings).

It was still early, so I had enough time to head east to the North Platte area to bird some of the hotspots there.  Although I had already found most of my possible targets, there were still some longer shots to try for. 

The first stop was Cody Park where I quickly found the semi-feral and non-countable Trumpeter Swans, and Snow and Ross’s Geese, but found little else besides the many wild Canadas.  Then I took a slow walk around the tennis courts that are surrounded by mature pines and spruces, but didn’t find anything in the conifers.  Nearby North Platte Cemetery had similar planted conifer habitat, including a row of pines full of Sapsucker holes – but there were no Sapsuckers to be seen.  The highlight there was a presumably mated pair of Flickers foraging together – one was “yellow-shafted” and one was “red-shafted”.

Next I was on to Scout’s Rest Ranch where several Rusty Blackbirds had been seen nearly 6 weeks earlier on the Christmas Count.  Just as I pulled into the parking lot 3 Blackbirds flew directly overhead – although I didn’t get great looks at them, they were the right size and shape of Rusty’s, and I saw no shoulder patches or striping suggesting they were Red-wings.  They flew off low to the northwest into an area of swampy woods with wet leaves on the ground – perfect habitat for Rusty’s.  So although I would have hoped for better views, I felt good about adding this bird to my NE statelist (#13).  I now only need Rusty Blackbird in a few more states within its regular range.


As I drove west toward my next stop I noticed a cattle feed lot and a cloud of blackbirds swirling around it.  As I pulled over a large portion of the flock was close to the road, and most were Starlings, though I picked out at least 10-20 Brewer’s Blackbirds in the swirling activity.  Not a new statebird but a nice “write-in” on eBird.

Then I was off to small Bowley’s Pond along the interstate.  It was full of mostly dabbling ducks and geese, including 2 Snow Geese (1 white and 1 blue form), and at least 10 White-fronts.  This would have been a great stop the day before, but those geese were old news now.

My last stops were around the power plant in Sutherland.  Although I didn’t pick out anything new, there were still a few highlights.  The first was at a small lake south of the power plant that was full of Mallards – maybe 5,000 or more.  And interestingy, the vast majority were males!  Check out these photos, first a shot taken of a portion of the lake with my iPhone –


Then a closer phonescoped shot –


Finally I made my way to a cooling pond at Sutherland that has numerous baffles on the surface that are preferred perches for loafing birds.  Here I picked up a few out-of-season birds that were new for the trip– 5 White Pelicans and 2 Double-crested Cormorants.  A nice conclusion to another most successful statebirding trip.

I ended up with 70 species on the trip, including 15 “write-ins” in eBird.  My tally of 13 NE statebirds was way over my hoped-for goal of 7, giving me 245 in NE – 20 over the old ABA threshold.  That should keep me over the threshold for many years to come.
