Lots of young Black Phoebes in the park recently. I think it's a "Phoebe boom"... The juveniles are a bit lighter with those brownish wingbars. Pretty vocal, too!

An unusual guest was visiting our stretch of river today. Large, probably eight to ten inches in length, with clear red and yellow markings on its head. Lousy pic at the end of my lens, but I believe it is a Red-eared Slider. I did see one here last summer.

When I saw this grey bird in the treetops, I got excited. Certainly it was something I hadn't seen before! Alas, a less excitable friend has just confirmed that it is merely a juvenile European Starling. Now, Starlings are all over the place around here, but I had never seen one in an attractive grey suit with a conservative black (not glaring yellow) bill.

This observation documents the current crowded avian activity in the river. Lots of small fish have attracted lots of hungry birds; and as in all societies, the big birds can get a bit pushy. This is a series of shots beginning with a fantastic catch by a Black-crowned Night Heron. No sooner does he pluck the fish from the water, than a nearby Great Egret flies into the spot. Not sure if it was attempting to steal the fish, but the heron took off, fish in bill, and landed a dozen feet away to finish its meal. The Egret, having taken the high ground, tried to look tough.

Spotted this small flycatcher moving around the lower branches of the trees in the eastern end of the main section of the park. Light gray, very pale beneath, with no obvious yellow. Thin dark line through eye (which is quite dark) with a white stripe above. No visible wing bars.

I have been photographing this Western Kingbird nest for a couple of weeks. On this day there was a bird in the nest, while another was feeding among the trees below. The reason I believe it is a Western Kingbird is a fairly clear view of the white outer tail feathers. Still no sign of fledglings.

This Snowy Egret was the fishing champ of the morning. I watched it catch three fish in less than five minutes. The second fish shown is a bit hard to make out, but I think it is one of the armored catfish we have been seeing around here.

This is one of the "group style" photos that I love to take. Much of the time, I have no idea what I am shooting at the moment. In this instance, I saw what I thought were two Great Egrets fishing. As I got closer, I realized that it was actually a Great Egret alongside a Snowy Egret. How cool! It was not until one of them had caught a fish, that from the middle of a circle of rocks only five feet away, a third head popped up. A Black-crowned Night Heron had been there all along, out of sight.

At the easternmost end of the islands are an odd assortment of Mallards. Several appear to be interesting hybrids. I suppose technically they could be called Domestic Ducks. This one has a dappled look and a black and white face.

This Double-crested Cormorant was on an adjacent rock to another cormorant. Though I couldn't hear any sound (I was quite far off), I could see them both vibrating their neck muscles. I have attached several consecutive shots (of one of them) to illustrate. From a distance they appeared to be "fluttering" their throats. I can imagine them making that "grunting" sound that I have been reading about.
