[cobirds] Larimer County Black-throated Blue Warbler

I found a male Black-throated Blue Warbler this afternoon near the parking lot of the Northern Colorado Environmental Learning Center in eastern Fort Collins (Larimer).  The "ELC", as most people know this place, by is located off East Drake Road about a mile east of Timberline.  I believe it is covered in the Larimer County section on the County Birding link on the Colorado Field Ornithologist's website.

The bird was near the northwest corner of the ELC parking lot.  Just a few feet north of the northwest corner of the parking lot is an outhouse and the start of the bike trail (which leads north to the suspension bridge).  Directly across the bike trail from the outhouse (i.e. east) is a big thicket between the trail and the river.  Winter Wrens have been in this same thicket in the past.  The BTBW likes this thicket, where it spent the entire afternoon getting aphids, and possibly leafhoppers, from a few different plants including Virginia Creeper and honeysuckle.  It also goes up from time to time into the boxelders and willows overtopping this thicket, again probably after aphids, and possibly midges.  It is very quiet.  I may have heard it giving a junco-like chip a few times, but not often.

Ken Ecton and I will be out there tomorrow morning at 7:30am if anyone wants to give it a go.  It would be a good night to fly, but who knows.
