[cobirds] Denver county red crossbills

2023-08-27 Thread wmrki...@gmail.com 
Just had a small flock (6-8) of red crossbills feeding on my sunflowers - 
NW Denver near Lakeside Amusement Park.  One male, at least two females, 
and the remainder were juveniles. New yard bird for sure!

[cobirds] Re: Bohemian Waxwing diet

2023-03-23 Thread wmrki...@gmail.com 
At our home in NW Denver (Berkeley Park) we have a dozen blue velvet 
honeysuckle bushes. This late winter we've observed flocks of robins, cedar 
waxwings, and Bohemian waxwings feeding on the small dried berries of these 
plants.

[cobirds] Re: Wings fall from the sky at Littleton

2022-04-02 Thread wmrki...@gmail.com 
Several years ago I witnessed a similar scene between two red-tails 
adjacent to the I-225 off ramp at DTC Boulevard.  They stayed locked 
probably for 10 minutes or so.

Actually, I posted this observation on Friday, September 10.  Not sure why 
it didn't show up here until Tuesday, September 14.
