[cobirds] Black Swift, Boulder County

[Peter Gent]

All,

This morning I hiked up to Ouzel Falls in the Wild Basin area of Rocky
Mountain National Park.  The usual nest site was occupied by a presumed
female Black Swift.  Also, I did not hear or see any Stub-tailed Wrens at
Calypso Cascades, where they have been occasionally in past years.  One
possible reason was the noise because there is more water now in the
Cascades and Ouzel Falls than I have ever seen on many trips before. I also
saw both Sapsuckers on the road in to Wild Basin just east of the large
parking area where the road is closed over the winter.

Cheers,  Peter Gent.
Boulder.

[cobirds] Lark Buntings - w. Arapahoe Co.

[Jared Del Rosso]

This morning (6/30), I was surprised to find an adult male Lark Bunting 
around Kent Denver School / Blackmer Lake in west Arapahoe Co. The 
encountered seemed fluky, but then I spotted five more Lark Buntings at 
Willow Spring Open Space in Centennial. These birds don't seem to come out 
to the Denver metro / w. Arapahoe area in late-June or early-July all that 
often, at least according to eBird reports. Wonder why they're here...

[cobirds] Fwd: DFO Website Contact - Birding Question

[Ira Sanders]

Birders,
I am posting this for an out of state birder who is looking for a guide for
next May.  His name is David Northrup and this is his email.
 

Ira Sanders

I will be in Denver for work in the third week in May 2018. I would like to
hire a guide for one or two days trips. I cannot seem to find a listing of
local guides. Can you provide a site that lists guides or provide the names
of any local guides. Thank you.

[cobirds] Purple Martins - Huérfano County

[Leon Bright]

COBirders--  Jim and Irene Thompson (of La Junta) just called to report a
pair of Purple Martins going in and out of a (nest?) hole in a tree about 15
miles west of Aguilar, in the mountains.  Jim is taking photos.  For those
of you who are new to birding in our state, this species very rarely nests
on the eastern slope.

Re: [cobirds] Re: Dickcissel plant associations

[DAVID A LEATHERMAN]

Very nice information, John.  While Dickcissels seem to occur in many different 
plant communities, as you point out, they are NOT everywhere.  I am struggling 
to see the keys to their occupation of a particular site or region.  Is it 
structure or food or both?  My botanist friend Dave Steingraeber from CSU told 
me tonight that he heard from a colleague that drought in the northern prairie 
states (Dakotas, etc.) is perhaps forcing birds from normal strongholds into 
other places.  The result is birds in novel areas or birds at abnormally high 
numbers in areas where they occur with regularity in low numbers.  Lush 
vegetation seems to be a key to where they settle for the summer but I suspect 
the prey base that lush vegetation supports is the real answer.  Whatever the 
answer(s), it is interesting.


Again, thanks to you and everybody who has chimed in on this issue.

Dave: We have been carefully observing the plant cover types where we are 
seeing the dickcissels. Myself and a range conservationist discussed this very 
topic yesterday on our trip to see Dickcissels south of Alamosa. Here is the 
San Luis Valley perspectivelist:

Tall Brome Grasses: Usually of nonnative grasses like smooth brome, timothy
Tall Grasses-Alfalfa complex: Birds are in a mix of these two plant cover types.
Barley: Today I heard one singing in a barley field. These are all cover types. 
Habitat types or plant associations usually refer to native plant potentials. A 
cover type is just the combo of plants that are currently on an ecological site.
Most of these types are currently being cut for hay. In which case, birds have 
moved to fencelines or uncut corners and edges. We will be looking at this 
population to see if we can see breeding evidence, aka Atlas procedures.

I have not seen or heard any Dickcissels in the San Luis Valley that are on 
native habitat types/plant associations. Not surprising since we lack true tall 
grass prairie ecosystems in our high desert shrubland communities.

I would be interested in hearing from COBIRDS folks about their observations of 
the dominant plant(s) in the areas where Dickcissels seem to be territorial 
(lots of singing on multiple days).  Of course, alfalfa has always been a crop 
that seems to attract Dickcissels, presumably because of the sulphur and white 
butterfly caterpillars found in these fields, and probably a lot of other 
insects like grasshoppers.


During this year when the Colorado prairie and foothills are lush with plant 
life due to much needed moisture over the last couple years, Dickcissels can 
exist in our midst and they seem to have choices.  Which choices are they 
making?  In addition to alfalfa fields, I have also seen them in 
salt-cedar/tamarisk (of all things, in this case near Nee Noshe Res south of 
Eads (Kiowa)) and in wild licorice (Glycyrrhiza lepidota) north of Nunn (Weld).


What other plants are you seeing Dickcissels favor?
