On this day, a pair of our Western Kingbirds visited the easternmost section of the park, east of Riverside. They perched in the top of a large tree and successfully plucked insects from the air, which they "tenderized" by banging them against the branches before dining.

Two Kingbirds in this park constructed a nest and produced two fledglings. After a week or so with the youngsters in the nest, it was abruptly abandoned and I haven't seen any Kingbirds return to that tree. Instead our small population seem to be very gradually expanding their range and I have begun to see them in the eastern section of the park and in the trees in the river. I sometimes see them singly, but often they appear in pairs, as in this observation.

Dining on live bees must be a bit like sampling very hot cuisine; you must be a bit cautious. At least that's the way this juvenile Black Phoebe seemed to be doing it.

I was walking to my car when this small moth (about 2 cm width) caught my eye Well camouflaged, my camera didn't want to focus on it, but I think it is a pretty good match for the Common Angle. It possesses the clear "paw print" dark patches on the distal forewing and that curved indentation on the outer edge of the wing lined in dark brown. The dorsal abdomen has paired brown spots that continue posterior until covered by the wings. What do you guys think?

The long tail and slender bill of this sweet voiced bird seem to indicate a Hooded Oriole. I tried for a long time to get a better photo, unsuccessfully, but I hope these are enough for an identification. This bird was seriously shy!

Right now the river is filled with small to medium sized fish, causing me to wonder if that might be the reason the Osprey have not yet returned. What can a big bird do? This Great Blue Heron is apparently able to grab them by the mouthful! I was a long way off when the heron made a stab into the water... but I took a photo just in case. I thought it had missed and was surprised when I edited the shot at home and saw a row of small fish in its bill. This bird can hunt!

The life of a Double-crested Cormorant, outside breeding season, can be a bit dull. Fishing... drying out... fishing... drying out. Fortunately in a metropolitan river like Los Angeles, other distractions can be found. These two are taking up gaming.
