Lewis's Woodpecker juveniles-video clip 2

-
This clip gives a nice view of the juvenal plumage of these Lewis's Woodpeckers including a good look at the of the warm chesnut tones on it's head. According to "Birds of North America" online there is considerable variation in juvenal plumage in birds in these post-breeding flocks but does note that "feathers of hindneck have white subterminal spots (not present in adult....)"--these white spots can be seen if the video is stopped when it's back is to the camera. BNA also notes that the tail feathers are more pointed than in adult plumage a feature seen at the end of this clip. One of the woodpeckers flies over to the top of a snag and has what looks like a winged insect in it's bill. It proceeds to either cache this food or try to dig more insects out? I have watched this clip over and over and cannot tell whether it is food caching or finding. This species is known for caching acorns in tree crevices (tho I didn't find anything about them caching insects) as well as using their bills to located insects in broken/open parts of snag trees. Does anybody have experience with this? 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
