Brunnich's Guille in Stonington, CT

Phil Rusch found this THICK-BILLED MURRE at Stonington Point, CT this morning. The bird soon flew north into the harbor and was later relocated in a more sheltered cove. Sadly, it was refound dead, floating in the water, a couple hours later, without signs of predation.

A Taverner's Cackling Goose in Rhode Island

Back on December 18, 2019, while helping a friend chase her life Pink-footed Goose in neighboring Rhode Island, we spotted two Cackling Geese that had been reported in the flock. Those two birds were pretty much attached at the hip. One was a bog standard Richardson's, being frosty-backed with a squared-off head and tiny bill. The bird next to it, which admittedly I didn't study for long, was certainly darker-backed and didn't have quite the same squared off head. Still, it was likely another Richardson's, but we were distracted at the time by the Pink-footed and a third Cackling Goose that proved to be much more interesting.

Cackling Goose #3 was on a different end of the flock and really stood out in that it didn't really stand out. Yes, it was smaller-bodied with a short bill. It was clearly a Cackling Goose. But it did a much better job of blending in with the flock than a Richardson's CACG would have. While switching between scope and camera I would often lose the bird for a little while.

Its upperpart pattern was rather muted, lacking the high-contrast pattern we see from Richardson's. For a Cackling Goose, it was on the large end of the scale. Most interesting, though, was the head/bill profile. The head was exceedingly rounded, a feature accentuated by the short bill that had a broad base. In profile, the forehead sloped almost seamlessly into the base of the bill. All of this is classic Taverner's Cackling. This structure held up throughout the observation and was not posture-dependent.

Subspecific ID of white-cheeked geese is fraught with difficulty, but Cackling Geese are easier than Canadas. Mlodinow et al wrote a nice piece on their separation in 2008 (North American Birds), though new information will continue to come to light regarding the taxonomy and ID of these birds. We still have a lot to learn, it seems.

Happy New Year

Happy New Year to everyone out there!

2019 was a fun one, as my birding was highlighted by a Self-Found Big Year in CT. Per the set of rules I ended up deciding on, I finished with 276 species for the year, amazingly close to the guesstimate of 275 I made at the beginning.

Not sure if I'll be putting the year into blog form after the fact (I had little time to blog about it as I went), but I will be speaking about it at some local clubs in addition to writing something for the ABA Birder's Guide, so stay tuned for those.

2020 should see a return to less local birding and much more of the non-birding aspects of my life that I love, though I will be traveling much more than I did last year, with trips to southern Africa (as CAS trip leader), Madeira (private trip with friends), and south Texas (for work, but I'll have some daylight to explore a bit) already on the books. In other words, 2020 will be a much more normal year for me.

All the best for a Happy and Healthy 2020.
