BAS Field Trip: Naked Birding
We started with a walk around the Logan Cemetery, which can be a great place in winter to find birds that are usually more typical of higher elevations or more northern latitudes. This visit was no exception, and we had a flyover flock of RED CROSSBILLS calling, plus a later lone crossbill that was probably a WHITE-WINGED CROSSBILL (although the "Type 4" Red Crossbill of the Pacific Northwest has a very similar flight call, and can show up in this area in winter). We also discussed the identification of Black-capped and Mountain Chickadees by voice after hearing some BLACK-CAPPED CHICKADEES, and found some RED-BREASTED NUTHATCHES.
From there, we went to First Dam, where we were able to identify some BARROW'S GOLDENEYES and COMMON GOLDENEYES before getting blown away by the strong canyon winds. We watched two BALD EAGLES flying over the reservoir, including one adult and one sub-adult. We also discussed how to tell the difference between the wild, native MALLARDS and the introduced "park duck" Mallards, which can look very similar. The wind was howling, though, so after a few minutes here we decided to move to a more sheltered location. While we were driving away, one car saw a HOODED MERGANSER from the road.
Our next and final stop was Rendezvous Park and the Logan River Golf Course. A flock of CANADA GEESE that flew overhead had one CACKLING GOOSE among them, a species that was on the state review list until just last year. We saw several mixed songbird flocks here, always including BLACK-CAPPED CHICKADEES but with various other species in attendance, including a BROWN CREEPER, several DOWNY WOODPECKERS, and one flock of about seven RUBY-CROWNED KINGLETS. The highlight of the day, however, was a single BEWICK'S WREN that was heard calling several times in one of these flocks. This is a very rare species for Cache County - there is a credible report of this species in the county only about once every three years, usually in winter.
We will publish the full 2013 field trip calendar in the next month or so, so keep an eye out for that, and in the meantime I'll see you at the Logan Christmas Bird Count next Saturday, December 15th. Email Bryan Dixon at bdixon@xmission.com to sign up if you haven't already.

Logan CBC Highlights

By the end of the day, the count collectively had tallied over 16,000 individuals of 92 species. That is at the low end of our averages, but given that fog hung over the valley for most of the morning, we felt pretty happy with that total. A more thorough analysis of the numbers of each species will be published in the next edition of the Bridgerland Audubon Society's newsletter, the Stilt, but here are some of the rarest species reported:
CACKLING GOOSE - Five individuals seen in a flock of 300+ Canada Geese at the Logan River Golf Course by me and Guillaume. This species was only split from Canada Goose in 2004, so most previous CBC'ers didn't try to count them. First documented in our count in 2008, seen again in 2009, and missed last year.

DOUBLE-CRESTED CORMORANT - One bird with an injured wing has been hanging out at the Logan Fisheries Experiment Station ponds for several weeks. This species has only been seen on our count on three occasions in the last 20 years.
WHITE-FACED IBIS - Three individuals were seen by several counters. Only one observation on our CBC in the last 20 years.
HOODED MERGANSER - Two females or immatures continuing at First Dam, seen by several observers. Seen about every other year on count day.
HERMIT THRUSH - One individual seen by me and Guillaume, but no photos. Found on our CBC about one out of every two years.
BEWICK'S WREN - One possible observation of this species was reported by Reinhard Jockel and Caitlin Laughlin. Craig Fosdick and I were not able to relocate this bird today. This species has never before been reported on our CBC since the count started in 1956, and will probably require additional documentation to be included in the final totals.
LINCOLN'S SPARROW - Two of this species were observed, which is quite remarkable since it has never been seen on our count before. One was a continuing bird found last week by Andy Kleinhesselink and relocated by Bryan Dixon and Jean Lown. The second was found and photographed by Kurt Kotter.
Lincoln's Sparrow photographed Dec 9 by Andy Kleinhesselink, linked from his Flickr account. This bird was relocated on the Logan CBC. |
WHITE-THROATED SPARROW - Another great find, continuing from Andy Kleinhesselink's discovery last week. Always a good one to look for on our CBC, found on 7 of the last 20 counts.
I photographed this White-throated Sparrow on Dec 10, but it was relocated on count day. |
(RED) FOX SPARROW - Found by Guillaume Peron and me. Fox Sparrows have been reported on only four Logan CBCs since the count started in 1956, and once in the last 20 years. The CBC doesn't typically record subspecies, so I don't know whether those previous observations were of the subspecies that breeds here, the Slate-colored Fox Sparrow, or vagrants of another subspecies. The Red Fox Sparrow breeds in northern Canada and the eastern states. According to eBird, the Red subspecies has only been documented in Utah once before. (There are a few other reports that I know of that are not in eBird). There is some indication that this group might get split in the future, elevating the Red Fox Sparrow to full species status, and some authors already consider them to be a separate species. Dennis Welker reported that he also thought he had a Fox Sparrow at Spring Hollow, but it wasn't clear to me whether he considered that observation confident enough to count, and he didn't know which subspecies it was.
Finally, I found two very interesting ducks at the Logan Sewage Lagoons, neither of which really "count" as species for the Christmas Bird Count, but they are noteworthy nonetheless. First was a "Brewer's Duck," a hybrid between a Mallard and a Gadwall. (More on Brewer's Duck here.) The second was another hybrid, this time between a Northern Pintail and a Mallard. What a beautiful duck!

One of the prettiest ducks I've seen, a hybrid between a Mallard and a Northern Pintail. I love that long pintail that curls up like a Mallard's tail feathers! |

Seattle Birds
Fox Sparrows are common over much of North America, and they can be found near my current home in Utah, especially in the summer. But there is variation among Fox Sparrows, and the subspecies found in Utah is not the same as the one in Washington. This is a Sooty Fox Sparrow I photographed near my parents' house in Issaquah.
A lot of people I talk to who aren't birders know what a chickadee is, but don't realize that we have several species in the U.S. One of my favorites is the Chestnut-backed Chickadee, a resident of mostly coastal forests and to me a strong reminder of the Northwest. This image of a Chestnut-backed Chickadee clinging to Douglas-fir cones seems an almost iconic reminder of my friends and family in Washington and Oregon, and of course of my avian friends there.

The Mystery of the Cackling Geese
In 2004 the American Ornithologists Union made a major change to birding in North America by announcing the split of what was formerly known as Canada Geese into two species. The larger of the two was to remain known as Canada Geese, and the smallest four of the eleven or so subspecies in the Canada Goose group would be known as Cackling Geese. This decision was based on genetic evidence that showed little to no interbreeding between these groups. This move was not unexpected by those who had been paying close attention to Canada Geese. The subspecies of Canada Gees were discernible in the field, and various subspecies or groups of subspecies had been elevated to species status in the past. However, it was a big surprise for most of the birding community, because, to be honest, most of us hadn't paid much attention to Canada Geese before.
In Utah, and probably throughout many parts of the U.S., this caused a stir. What was once one of the most common and familiar species in the state was now a pair of strangers. The safe thing to do in this situation was to assume that all previous records of Canada Geese applied to what was still known as Canada Geese, because the most common species here, the Great Basin Canada Goose, was still considered a Canada Goose. However, some records already existed of Cackling Geese in Utah, namely museum specimens. But the Utah Bird Records Committee decided to put the Cackling Goose on the state review list so that any records of this species in the state would be reviewed by a panel of experts.
Now that more people are looking for Cackling Geese, more people are finding them. In the four or five years since the species became a species, there have been over 20 records of Cackling Geese in Utah. However, I think the Records Committee must remain unconvinced, because few records have been submitted to the committee and even fewer have been accepted. Part of the problem, I think, is that the details of Cackling Goose identification were not well worked out. There were conflicting opinions on various websites about the traits that distinguish the largest subspecies of Cackling Goose (Like Taverner's Cackling Goose, seated at right in the photo above, and Richardson's Cackling Goose, in the back of the photo below) from the smallest subspecies of Canada Goose (like the Lesser Canada Goose, in the foreground of the photo below). Thankfully, I think that confusion will soon come to an end. A brilliant article published in the latest issue of North American Birds outlines in thorough detail how to tell the subspecies of Cackling Goose from one another, and from the smallest Canada Geese. I'm hoping that this article will be just the thing to help our knowledge of Cackling Geese advance in Utah and elsewhere. In the meantime, I intend to continue to submit records to the Utah Bird Records Committee until a pattern of occurrence has been established. Based on one year of actively birding in Utah, I think we will soon solve the mystery of the Cackling Geese and realize that this species, although rare, occurs annually in winter in Utah.
