A tree pipit (which I have seen on Attu) apparently nests on the ground, but 
sings from low branches of a tree!

RE: [cobirds] Weekend Birding/Weld

[jhmoss]

Are the tamarisks all dead or just individual trees?

 

If they are all dead in large groups along the river, then it is the
beetle.  A predatory beetle was brought in to eliminate the Tamarisks.  It
was tested for more than 10 years to see if it was going to be an
eco-disaster.  Scientists figured it would do a mile or 2 in a year.  Once
the tammies in an area are dead, the beetle dies. So no eco problems and the
plan was put into place.

 

So the scientists calculations were it would take dozens of years to clear
up the Colorado River system.  The beetle was first released in CO and by
the second year it was in the Grand Canyon.  It kills large sections of
tammies.  Of course, when dealing with nature, nothing went as planned.  Too
successful.

 

The reason why the tammies are considered bad is, some estimates put an
additional 50% of the water in the CO river system in the tammies alone. No
native plants can compete with them.  Problem is tammies can grow overnight
and willows take a decade to recover.  So there are a lot of treeless
sections of rivers in the CO river system.

 

That is also why if you are a boater you have been told not to go some
places because they are trying to re-introduce the willows.

Speaking of the fields north of the campground... it looks like there's
a campaign to eradicate Russian olive. Anyone know who's behind that?

Hi all

 

Lone Tree Creek crossing at Weld CR 110 (just west of Hwy 85 in Nunn) had a
good smattering of birds:

*   Wilson's Warbler
*   Orange-crowned Warbler
*   McGillvray's Warbler
*   Gray Catbird
*   Green-tailed Towhee
*   Brown Thrasher
*   Lapland Longspur (2) flyover and seen briefing on ground with Horned
Lark
*   American Goldfinch
*   Song Sparrow
*   Yellow-beasted Chat
*   Brewer's Sparrow
*   White-crowned Sparrow
*   Mourning Dove
*   American Kestrel
*   Eurasian-collared Dove
*   Lark Sparrow

Weld CR 124 pond-few miles west of Hwy 77 hosted ducks, geese, Prairie
Falcon, Swainson's Hawk, Golden Eagle, Greater Yellowlegs, Baird's and Least
Sandpiper.

 

Galeton Ponds heating up. Burrowing Owl still lingering about one mile east
of Weld CR 74/61 (ponds). Franklin's Gull (34), Long-biled Dowitcher (12),
Stilt Sandpiper (5), Black Tern (8), Forster's Tern 91), Greater Yellowlegs
and Wilson's Phalarope.

 

Crow Valley Campground I got 37 species, highlights include Red-headed
Woodpecker, Red-naped Sapsucker (2), Laplong Longspur flyover NE corner,
Red-breasted Nuthatch, empids, Gray Catbird, Swainson's Thrush,
MacGillvray's Warbler, and Ruby-crowned Kinglet. Others reported a vireo
species, three Great Horned Owl.

 

Crow Valley question: Has anyone ventured out to the north-south mature
tree lines at very western edge of farm property out the (west) back gate? I
have not and wondered about how close you can get to them or in them? Or if
worth the hike out to them? I've been out on the farm property just never
walked that far west.

 

Some photos below.

[cobirds] Russian olive removal

[DAVID A LEATHERMAN]

The Russian-olive removal at Crow Valley Campground was done at the behest of 
the US Forest Service who is in charge of the area.  These days the USFS does 
almost all on-the-ground work, except firefighting, through contractors.  I 
believe the removal of the olives at Crow Valley Campground was performed by 
some locals out of Briggsdale.  My guess as to how this all went down is that 
there was a pot of money in a veg management account that would have to be 
returned if not spent by September 30 (the end of the federal fiscal year), 
somebody in Greeley or Washington knew about, or ascribed to, the paradigm that 
R-o is evil, also knew that giving a contract to the two guys with a dog, 
chainsaw, magnetic sign and pick-up would give somebody brownie points for 
"hiring local", and it was done deal.  As far as I can tell, it was a quick and 
dirty operation with no removal of the cut wood, no treatment of the stumps, no 
replacement planting of "better" species, no interpretive material on-site or 
explanation given to the Campground Host (in case he was asked why it was 
done).  If somebody knows a different story about how this all happened, I am 
open to correction.

As stated, the paradigm amongst most CO natural resource agencies, be they 
federal, state, county or city, is that Russian-olive is evil and deserves 
eradication.  This is a fairly new school of thought.  Following the Dust Bowl, 
R-o was planted widely promoted and planted as a helpful remedy on the Great 
Plains.  The federal Soil Conservation Service (now the NRCS) was its biggest 
promoter.  R-o grows well in harsh places and we all know the world is getting 
harsher by the minute.  The Colorado State Forest Service I used to work for 
has the last government tree nursery standing in CO and grows/sells 
approximately 2 million seedlings of all types a year.  They only quit offering 
R-o in the 1990's, mostly because it was PC to do so.  We all know the tree is 
a mixed bag, and considering only the issue of attracting birds, it is 
decidedly a positive.  I have extolled the positive aspects of this tree for 
birds for many years.  These efforts started out not so much as promotion of 
the tree but as an effort to "stand up" for it a bit, and balance the rhetoric. 
  The knocks against it are: 1) it has potential to take over riparian areas to 
the exclusion of native, better trees like willow and cottonwood, and 2) it 
doesn't host very many insects, and, thus, doesn't support a very robust set of 
nesting birds.  The fear of riparian area take-over has been erroneously 
extended to upland sites (which Crow Valley essentially is since it rarely 
experiences creek bed flow any more).  I have only seen the total takeover and 
stagnation of riparian areas in a limited number of places in CO, mostly along 
the Arkansas e of Pueblo.  In my mind, tamarisk (aka "salt-cedar") is way worse.

The primary insect R-o does have, an aphid (Capitophorus elaeagni), is very 
attractive to birds.  The fruits are very attractive to many birds including 
warblers, woodpeckers, flycatchers, thrushes, waxwings, mimic thrushes, 
finches, sparrows and many others including even upland gamebirds and gulls.  
Wood ducks love them.  When discovered, the 1st or 2nd State Record 
Brown-crested Flycatcher, Fork-tailed Flycatcher and Tropical Kingbird were in 
or near Russian-olives, no doubt using fruits to sustain their wayward 
adventures. Hey, Duane, any chance the Sulphur-bellied Flycatcher was doing the 
same?  Thickets are used by certain marquis birds like cardinals and cuckoos as 
nest sites.  Owls like long-ears roost/nest in R-o thickets, and I have even 
seen a pygmy-owl at low elevation in winter in a R-o thicket.

I am not sure what birders should do but I think the approach SeEtta mentions 
of at least injecting some balance into veg management planning early-on is 
good.  The resource managers, for the most part, have not heard our point of 
view that the tree could be good, and they need to hear it as something to 
weigh when considering the final plan.  My problems with every R-o 
"eradication" project I've witnessed are:

  *
Major assault on peace and quiet
  *
Never get them all, miss many small trees
  *
Never enough $ to plant, establish and maintain "better" species
  *
Never account for sprouting that will have the site right back where it was in 
10-20 years
  *
Never account for recruitment by bird droppings and seeds floating in on moving 
water
  *
In net, just dumb these areas down as a bird habitat and rec experience for 10 
years minimum

[cobirds] Hawk i.d. Storm Mountain, Larimer Cty

[Dave Hyde]

HI CObirders,,
At 1.25pm today as I looked out my kitchen window I saw a large 
hawk fly upwards and over the house. All I saw was a spread tail with many fine 
bands. I grabbed my binoculars and camera and went to the front of the house to 
see the hawk land atop a pine tree. I spotted it and thought, ‘that looks like 
an Osprey! Better take a picture.’ So I did and got 3 photos before the bird 
flew away. As it went it looked like it had a white rump. This is the best 
photo I got. Can anyone please tell me what hawk this is? – Dave Hyde/nr Storm 
Moutain, Larimer Cty.

Hi Dave!
Thanks for mentioning the white rump field mark. This looks like a
Ferruginous Hawk to me. On its upper side there are the diagnostic "three
points of white," the third point being the rump white patch and two white
patches on the "wrists."
The birds are happy, and so am I

Cinnamon, Your photos show Baird’s Sandpipers rather than Pectoral. Note black 
legs. Legs are yellow for Pectoral. Pectorals are even larger. The smaller peep 
in one of the photos is Semipalmated Sandpiper. Here is a photo of a couple of

Juvenile Red-tailed Hawk, check out light western juv. in Sibley. Bands on
tail from Dave's description. Also, no feathered legs that Ferrug would

[cobirds] Re: Russian olive removal

[Laura Gorman]

Thank you for this overview!  I always wondered how to balance the positive 
value for birds with the impetus to eradicate.  I sure see a lot of birds 
using the R-os here inCanon City.  Maybe thinning is the best or most 
realistic approach.

[cobirds] Bird Conservancy of the Rockies - Barr Banding Report, September 15

[meredith]

We had several slow days post-storm and there have been various reports 
about birds showing stress or worse due to the weather and probably the 
smoke from the fires.  So we were really pleased to band 85 seemly healthy 
birds today, including 64 warblers of 6 species, most of whom were carrying 
some fat.  Wilson's as usual led the parade, but we had a total of 17 
species.  Here's the breakdown for the day:

Eurasian Collared-dove 1 
Downy Woodpecker 2
Dusky Flycatcher 2
Cordilleran Flycatcher 1
Warbling Vireo 1 (this bird was leucistic, and very similar to one we 
caught last year)
House Wren 1
Ruby-crowned Kinglet 2
Orange-crowned Warbler 6
Yellow Warbler 2
Yellow-rumped Warbler, Audubon's 3
Townsend's Warbler 4
MacGillivray's Warbler 1
Wilson's Warbler 48
Brewer's Sparrow 1
Song Sparrow 2
Lincoln's Sparrow 7
Gambel's White-crowned Sparrow 1

If you'd like to visit: Due to restrictions related to Covid-19, we are 
requiring visitors to make a reservation and we will have only 6 visitors 
at the station at a time. We are doing three one-hour time slots, from 8-9, 
9-10, and 10-11, on Tuesdays and then Thursdays through Sundays, through 
October 11. There is a $5 per person fee; scholarships are available to 
those unable to pay. All visitors, staff and volunteers will be wearing 
masks and people will be expected to socially distance. To register and for 
more information go to

Re: [cobirds] Hawk i.d. Storm Mountain, Larimer Cty

[Joe Kipper]

Yes, this is a definite juvenile Red-tailed. When I see birds like this in 
the field I don't really take note of the field marks like a should I just 
say "this is a Red-tailed because of the GISS," but this is a good 
opportunity to note the field marks since Osprey and Ferruginous Hawk were 
suggested. This bird is paler individual so it doesn't have the "helmeted" 
appearance that most adults and some very dark juveniles have. The "three 
points of white" field mark is a field mark that is useful when looking at 
the dorsal side of soaring buteos. Because this bird is perched, you can't 
even see the "wrists" mentioned by Caleb that would be white on a Ferrug. 
White speckling on the scapulars is another field mark of RTHA. Adult 
Ferrug would have orangish back with steel-blue primaries and juvenile 
Ferrug would have a uniform brown back. Unfeathered legs are also a huge 
field mark, thank you Todd D.
Good Birding everyone! In a few months we will have plenty of opportunities 
to study the many buteos that winter here and their endless myriad of 
unique color morphs and plumages.

RE: [cobirds] Hawk i.d. Storm Mountain, Larimer Cty

[Dave Hyde]

Thank you all for your suggestions. I accept the pale Red-tail, possible 
Krider’s hawk (even though looking at the photo I thought there’s no way this 
can be a Red-tail: white head, white rump, barred tail!). But there is more to 
the story of this pale red-tail. I was looking out the kitchen window and the 
bird flew up from below the window,  which is when I saw its tail. I got to 
thinking, what would any large hawk be doing on the ground outside my window? 
So I went and looked on the ground there for any signs of avian mayhem. And I 
found … a complete wing of a Yellow-rumped warbler! There were no excess 
feathers or body anywhere although I later found the other wing, also intact. 
Whatever had got this warbler – and it may not have been this hawk as the wing 
feathers were only slightly supple as if the bird had died yesterday or early 
in the morning – had clipped off its wings and carried off the body! In fact, I 
had the impression that the pale hawk had something in its grasp as it landed 
atop the tree because it looked down at its feet when it alit. I dunno, this 
was certainly a strange hawk encounter. Here’s a photo of one of the warbler 
wings, and thank you all again for your advice – Dave
