Hello, birders. I tarried in the vicinity of Prince Lake No. 2, eastern Boulder County, early this sunny Sunday morning, Oct. 23. I found nothing that will cause a stampede of birders to visit the site, but the *white-crowned sparrows* and collared-doves (genus *Streptopelia*) were interesting.
Here's the distinctive flight call of one of the *white-crowned sparrows:* <https://lh3.googleusercontent.com/-Iy0-EY94hM8/WA07Na4RKMI/AAAAAAAAWBk/Bwo2EznZPK0By3Mw43VqV40WL52XST-zQCLcB/s1600/Screen%2BShot%2B2016-10-23%2Bat%2B4.14.18%2BPM.png> Note that the flight call is double-banded, rising from 7 kHz to 9 kHz, duration about 85 mS. Classic for white-crowned sparrow. Meanwhile, at least one of the many *Streptopelia* doves was an *African collared-dove.* In the pic below, note how the primaries contrast only weakly with the upper-parts. On *Eurasian collared-dove,* though, the primaries are typically much darker than the upper-parts. <https://lh3.googleusercontent.com/-ob1D0F58w_4/WA0754tt1HI/AAAAAAAAWBo/aucheNW8W38-gGuCgl3ZqGGRkW-FcXY8wCLcB/s1600/EUCD%2BIMG_2877.JPG> The complete eBird checklist, with additional white-crowned sparrow audio and more African Collared-Dove photos, can be viewed (and heard) here: http://ebird.org/ebird/view/checklist/S32174916 Ted Floyd Lafayette, Boulder County -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
