[cobirds] BBS Routes available

            We invite qualified observers to participate in the Breeding Bird Survey "BBS." Participants must have the skills to identify the likely species on their routes by sight and by sound.
            Since 1966 (1968 in Colorado and the West) the Patuxent Wildlife Research Center, originally US Fish & Wildlife Service, now the Biological Research Division of the US Geological Survey, has sponsored the Breeding Bird Survey program to monitor birds across the US (and Canada, with the Canadian Wildlife Service). In 2012, volunteers ran almost 3000 routes in the US & Canada. Scientists use BBS results to derive population trends for the species that the system samples well.
            Colorado has 132 designated BBS routes, and we consistently run more routes than all other states in the U.S. except Texas and California.
            A BBS route covers 24.5 miles. Observers record all the birds they hear and see during a 3-minute stop, then drive a half-mile to the next stop. You run the route, once only, during the peak of the songbird singing season, from May 25 on the plains to July 15 in the high country. The ability to identify species by sound is crucial--I estimate that I record 75-85% of the birds on my routes by sound, not sight.
            The observer should have the ability to identify, by sound and sight, most of the species likely to occur along that route. On my routes, I identify over 75% of the birds by sound, without ever seeing them. We seek a commitment of three years, because the BBS prefers route data run by the same person for at least 3 years.
            Let me know if you would like one or more. The following list is organized geographically (sort of). I hope that we can fill most of them with qualified observers who have good ears.
            The following lists the available routes; I can send more detailed descriptions to you if you'd like to consider one but want more information.
 
  "I especially enjoyed the first few pre-dawn stops along the wetlands area of Poncha Creek—the dawn chorus there was often a tad overwhelming.  An experience I will never forget." – Tina Mitchell

[cobirds] Eastern phoebe Boulder Creek

There was an eastern phoebe under the 75th street bridge at Boulder Creek, flying back and forth and calling, this morning around 10:30. We got a recording and poor photos with an iPhone. FOS, presumably the same one who has been here for a couple of years. -Elena Klaver and Topi Martinez

[cobirds] Greater Scaup,Denver,CO

I went on a Greater Scaup search today and found some. In a private pond on Pinehurst Golf Course {Denver} I saw 12 Greater Scaup, along with 1, Canvasback, and 4 Hooded Merganser. Tis the time for these Scaup to migrate. I saw 4 Greater Scaup at this pond one week ago. 
 
At Marston Reservoir today,  [Denver County], was 1, Greater Scaup, 2, Horned Grebes, and the common Dabbling Ducks seen this time of year; Gadwall, American Wigeon,  and  Green-winged Teal.  I counted 4, Common Goldeneye along with Ruddy Ducks at Marston today. One  Lesser Black-backed Gull, along with many Ring-billed Gulls were present at the Reservoir.
 
Happy Birding,

[cobirds] Pine Siskin in Pueblo

COBirders,

  This post probably will be of interest mostly for our less hard-core subscribers.  This morning a solitary Pine Siskin visited my back yard, mingling in with a few American Goldfinches who are molting more yellow feathers in anticipation of spring.  A single Pine Siskin is a rarity in that this species is definitely one that loves to flock.  These birds are also very undependable about showing up at any particular place in a particular season.  They usually aren’t seen in our state at lower elevation in warm weather, however.  Siskins used to be fairly common at my Pueblo feeders but this one was the first I’ve seen here in a couple of years.  Just goes to show, even relatively common birds can be interesting and fun.

Leon Bright, Pueblo
