Final songbird #s from Lucky Peak

Hi Folks .... (scroll down for a few photos)

I was delayed in getting to this because a day after closing up shop (on Oct 15) I flew east for a high school buddy's wedding in the Catskills Mountains of NY (awesome fall colors! - 1st time in many years that I've gotten to see that) and a short family visit. Thus, I just got done counting & re-counting the #s. Here we go:

During autumn 2007 (16 July to Oct 15), we captured 5771 birds of 56 different species. Our netting effort this year was 4116 mist net hours; this effort is lower than usual because we experienced a number of rainy and/or windy days that either prevented us from netting or reduced the number of nets that could be opened. The 2007 capture rate of 1.40 birds per mist net hour (which comes to 70 birds on an average day on which we open all 10 nets for 5 hours) is the 2nd highest in the 11 years of the study (2nd to the record season of 2006, when the capture rate was an amazing 1.71). Thus, if anything we are seeing a slight increase in captures over the years for a number of species. And, this is reflected in the fact that 2007 set record years for 8 species (and several others were tied or close 2nd). The new records set in 2007 are (in numerical order):

Dark-eyed Junco 1111 (previous high of 918 in 2006)
Yellow Warbler 290 (previous high of 186 in 2001)
Warbling Vireo 216 (previous high of 193 in 2006)
Cassin's Vireo 117 (previous high of 114 in 1999)
Brewer's Sparrow 87 (previous high of 58 in 2000)
Swainson's Thrush 26 (previous high of 20 in 2006)
Northern Pygmy-owl 10 (previous high of 5 in 2000)
Steller's Jay 4 (previous high of 3 in 2001)

Interestingly, 2007 was the first year in which Ruby-crowned Kinglets (shown here) were not the most abundant species (we caught 788; 2nd to Dark-eyed Juncos this year) and only the 3rd time we've not banded at least 1000 of this species in a season. We lost so many days and partial days to weather during the RC Kinglet peak (mid-Sept into October) that this result isn't surprising. But, it really was a stellar year for the juncos ...


Rarities/highlights from this season included the 5th Blackpoll Warbler we've banded at this site (Sept 7), our first capture of a Black-throated Gray Warbler (Aug 19), our 5th American Redstart (Aug 22), our 4th ever Green-tailed Towhee, and 4 Golden-crowned Sparrows (Sep 17, 21 [2 birds] and Oct 7). Also, in early August we captured a Willow Flycatcher that was previously banded by someone else (don't know who or where yet...).

Enjoy the late fall/early winter birding!
