Common Yellowthroat with different song

-
As I walked on the "wetland bridge" walkway over the currently dry marsh area, I heard a song I with which I was unfamiliar. I was surprised when I found that the Common Yellowthroat in these pics was giving that song. It's song sounded nothing like the wich-e-ty, wich-e-ty, wich-e-ty that is associated with this species. I was told today that there is a subspecies called the "Brownsville Yellowthroat" that has a very different song. I found some brief information about this subspecies, Geothlypis trichas insperata, but I couldn't find a recording of its' song to listen to.
Though "Birds of North America" online notes subtle plumage differences between this and other subspecies, though it didn't indicate if these were distinguishable in the field. I will post about my experience on Texbirds listserve and maybe someone will have further information. 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
