Found a brown-fronted probable hybrid BlackXEastern Phoebe in Coaldale,CO

-
Yesterday I found this brown fronted probable hybrid BlackXEastern Phoebe up the Arkansas River in a tiny town of Coaldale, CO. This location is about 33 miles west of where I had seen my first brown-fronted hybrid phoebe in late March of this year. This bird was about 80 feet away so I wasn't able to get a very good photo and cannot say if this bird looks like the one I saw in March. Due to the many nestings between presumptive Black and Eastern Phoebes in this area, I believe this is a BlackXEastern hybrid and that the brown-fronted plumage is a result of the hybridization. By the way, I did not do any editing other than cropping this pic so it would give the most accurate representation of the coloration and shading. I would add that this phoebe is not nearly as black as most Black Phoebes I have seen and photographed in this area (or other areas for that matter). The brown coloration on the crown of this bird is best viewed by double-clicking on the pic to enlarge it further.
The pic below is the brown-fronted probable hybrid BlackXEastern Phoebe that was associating with a presumptive Black Phoebe near Canon City at the end of March, 2011. It is certainly possible that this brown-fronted hybrid moved up river because I have not been closely checking the phoebes at my friend's place since they looked like they were going to nest and were very sensitive to disturbance. So I don't know for sure if the brown-fronted hybrid I was seeing there has been around for almost a month, plenty of time to move up to Coaldale. It would also be interesting if this brown-fronted characteristic might be occurring more than once as a result of hybridization.  Again, best viewed by double-clicking on this pic too. 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

-

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
