Hybrid BlackXEastern Phoebe: a second juvenile

-
While watching for the Black, Eastern and hybrid offspring Phoebes I have been following in Canon City,CO I spotted a second hybrid juvenile. It was easy to tell that this was another juvenile as it's appearance is substantially different from the first hybrid juvenile. The top and middle pics are of the second hybrid juvenile while the third is one of the pics I took of the first hybrid juvenile I found a week ago.
This second hybrid juvenile looks mostly like an Eastern Phoebe with a whitish throat contrasting with dark head, smudgy sides (though there seems to be some rather black portions and smudgy areas 'leak' across breast (similar to Black Phoebe but not completely dark across breast and Eastern Phoebes in juvenal plumage often have this). The tips of the rectrices are quite sharp, a characteristic of juvenal plumage for Black Phoebes and possibly for Eastern also (Birds of North America online not very clear on Eastern. It lacks both in the photos, and in my observation through my spotting scope, yellow wash on belly and underparts that is prominent in juvenal plumage for Eastern Phoebes. Other plumage characteristics not seen in photos or when I watched the bird in my spotting scope. Though this bird is clearly different in appearance than the first hybrid, it is in my opinion intermediate in plumage between Black and Eastern Phoebes. SeEtta

Spotted Sandpiper Chicks, 3 more days older

-

Two days when I went to check on the Spotted Sandpiper family at Florence River Park I thought they had likely perished--there were two men engaged in gold panning right where the parent sandpiper had been and they had dug some of the sand from the bank where I last saw the sandpiper chicks. Arggh, I was afraid that all this activity, plus a large off leash dog with these people, would have scared the parent away and even if the chicks were successful in hiding in the vegetation they would not survive without a parent at their young age. What a surprise when I returned that evening for one last check to be accosted by the parent sandpiper calling loudly and challenging me by walking right towards me (and my dog). It took awhile for the parent to settle down and for one of the chicks to walk in some grass where I could spot it--the parent had moved the chicks about 150 from the river into an area with a lot of vegetation. I returned day before yesterday and refound the parent and ...

Recently fledged Common Raven

-
Image
At the end of March this year I spotted a Common Raven going into a crevice above a rock face of a local cliff area called Castle Rock (as part of it looks sort of like a castle). I started watching this area and observed a pair of Common Ravens spending time around this location. On March 27 I spotted one of the ravens inside the crevice which now had what looked like nesting material in it--the photograph of that is the second pic here. I continued off and on to check this apparent crevice nest. At the end of May I saw what appeared to be a nestling inside the crevice. I continued birding in the riparian forest across the Arkansas River from this cliff area. When I was about a quarter mile away I heard a lot of raven racket and walked to a spot where I could see the cliff area through my binoculars. I could see a lot of raven action with the parent birds calling loudly so I expected that the nestling may have fledged or they were trying to get it to fledge. I went back t...

Band-tailed Pigeons, the mountain pigeons

-
Image
I spotted a small flock of about 9 or 10 of these Band-tailed Pigeons in a tiny unincorporated town called Greenwood which is south of Canon City about 20 miles (via winged flight). The homes in Greenwood are right up against the San Isabel National Forest and forests are the habitat for these mountain pigeons. The white collar on the nape of this species can be seen in the pic above.  The broad pale gray terminal band on a darker upper tail (and below the light undertail coverts) is best seen in pic below.  SeEtta
