[cobirds] free flicker nesting box

[Douglas Schoch]

I have a weathered, but functional flicker box available if anyone is 
interested. It attracted flickers a couple of times, but ultimately it became a 
squirrel apartment. The major streets closest to my house are Smoky Hill and 
Himalaya. Please let me know if you'd like to pick it up. 

Doug Schoch, Centennial, Arapahoe County

Observation start time: 09:00:00 
Observation end   time: 15:00:00 
Total observation time: 6 hours

Official Counter:Gary Rossmiller

Observers:

Visitors:
Several people stopping to ask about us. Larry and Mike spent most of the
first hour with us. Skye spent the second hour and may volunteer. 


Weather:
Very pretty day, increasing clouds and wind until past noon, then a bit
calmer and more sunny. Windiest around noon B5-B6, yet often calm during
any hour. Winds shifting almost every hour; out of the west or north. Temp
from 15c up to 20c, barometer falling 24.43 inHg down to 24.36. Cloud cover
started with clouds to the west, they gradually moved east, sunny last
hour. Horizons visible. Trail is dry and hardpacked.

Raptor Observations:
Local TV entertained me on the hike up, followed by a local RT. Most
raptors to the east around eye level, except one SS scrapping the tree tops
very low to the east of the ridge. One UA very high this afternoon
overhead. Started out at a good clip this morning, then numbers dwindled.
Local raptors and song birds disappeared till later. 

Non-raptor Observations:
Trail steady but not busy. Woodhouse, magpie, mtn chickadee, ravens,
bushtit, swifts, solitaires. The white throated swifts tended to come by in
pairs very close to the ridge. A few were quite a ways up.

Predictions:
Is our weather to good for migration? I'm predicting another day of 12+
raptors.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:

More site information at hawkcount.org:  
https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders of any skill level are always welcome.  HawkWatch at
Dinosaur Ridge is generally staffed by volunteers from about 9 AM to around
3 PM from March 1st to May 7th.

Directions to site:
>From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the southwest end of lot to the hawkwatch site. The hike starts heading
east on an old two-track and quickly turns south onto a trail on the west
side of the ridge. When the trail nears the top of the ridge, turn left,
head through

This article hasn't gone to final press yet as far as I know.  When i was
looking at it the other day, there was a note that it was still undergoing
review and editing and that this was a preview .   I have bigger issues
with their methods and conclusions but that is for another email.

Someone should have done better proof reading of this document. "naive

[cobirds] Tonight! Fort Colllins Audubon Society hosts “Army Cutworm - Colorado’s Migrant 'Miller' Moth”

[Andrew Monson]

 *Fort Collins Audubon* invites you to join a *virtual program* (via Zoom) 
featuring *Whitney Cranshaw*, professor emeritus of Entomology at Colorado 
State University. Whitney will be presenting *"Army Cutworm - Colorado’s 
Migrant 'Miller' Moth” *tonight, Thursday, April 8th, 2021; *Announcements 
at 7:00pm and Program at 7:20pm.*

* Enter the following link on your web browser at or before 7 p.m. and 
follow the instructions to join the meeting:  
https://us02web.zoom.us/j/84890366654 
 *

”Annual migrations of some kinds of North American butterflies and 
dragonflies (as well as birds!) are well known and often highly 
popularized. However, perhaps one of the most interesting migration stories 
in North America involves the army cutworm with its low elevation/high 
elevation migration cycle that occurs entirely within the borders of the 
United States and is most clearly evident in eastern Colorado. The focus of 
this evening’s discussion will be this rather notorious “miller moth” and 
explore the life history and habits of this insect and the various impacts 
it has on ecology and human interests. 

Whitney Cranshaw is presently an emeritus professor of entomology at 
Colorado State University, following retirement in July 2020. During his 37 
years at Colorado State he primarily worked on issues related to the better 
understanding and management of insects that affected horticultural plants 
in the state.”

[cobirds] Re: Bluebird dearth

[Sally Waterhouse]

In Chaffee County we have noticed a difference as well this year.  We 
noticed some very large flocks of Mt. Bluebirds in March but those seem to 
have disappeared now and resident birds that are often around nest boxes by 
this time seem significantly reduced.  Mt. Bluebirds were one of the 
species that were found here as victims of the September snow event.  We 
have a county wide nest box monitoring program here that may eventually 
provide some insight.
