Eastern & Black Phoebes share wetland

-
I birded Pathfinder Park near Florence,CO this morning to see if the juvenile Black Phoebes were still there. I only found one of the two juvenile Black Phoebes and it was calling frequently as it fed in the wetland area. Then a second phoebe flew into sight. I thought this was the second Black Phoebe, but no--it was a juvenile Eastern Phoebe. I got the top pic of the two as they perched quite near each other. They were about 75 feet away and I took the pic handheld so it is not great but shows how much more brown the Eastern Phoebe is, though the cinnamon edges to the juvenile Black Phoebe's plumage clearly stands out.
The two phoebes foraged near each other, seemingly without problem. However, they did have a fussy interaction at one point but then returned to sharing this small wetland. As I turned to leave the Eastern Phoebe flew out of the wetland and landed about 25 feet from me. It proceeded to forage out in the open and I was able to get the bottom two pics of it that show off it's plumage fairly well. The yellowish gape and bill flanges, found on young birds, is visible in bottom pic. However, the classic yellowish wash on the underparts on not visible in these pics and frankly not visible in the field--possibly a function of the light conditions.
Birds of North America online well describes the other juvenile plumage characteristics: "Wing coverts tend to have cinnamon-buff edgings, along with feathers of the lower back, rump and the upper tail coverts. This edging of the greater and median upper (primary and) secondary coverts gives birds in Juvenal plumage faint wing bars." The bottom two pics are of very good quality so can be enlarged by double-clicking on each of them for great close-ups. 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
