Joan and I found a hatch year Canada Warbler at Middle Lake in Golden Gate Park this morning at about 10:50. It was on the west side of the lake, north of the parking lot, in a deciduous tree behind a bench. That's by the little grassy meadow by Chain-of-Lakes Dr. The bird was and intense gray tending toward bluish from head to tail. The throat and all of the underparts I could see in the few moments I observed the bird were very bright yellow. This individual had a striking round eye-ring and did not have wing bars. On the negative side I did not observe any streaking across the breast and I didn't get a look at the undertail coverts to confirm they were white. A second warbler flew in as I was trying to show the bird to Joan and both flew off. Couldn't tell what the second bird was, but it looked somewhat like a Common Yellowthroat from below. There was also a Wilson's Warbler and a Pacific-slope Flycatcher in the vicinity. A Belted Kingfisher was on the lake and a Nuttall's Woodpecker was calling from near the warblers. Over at North Lake we picked-up a Western Wood Pewee and a Hairy Woodpecker.
Middle Lake notes: RPD neglect apparently has killed the swamp cypress on the island. A heritage tree that was probably planted around 1890. It's either dead or dormant for a record period of time. The willow grove at the NE corner of the lake that was habitat for loads of birds over the years is dead and gone. The place is quite the mess. However, there is water in the middle of the lake where neglect even wiped out a lot of the bulrush. All in all, a most unhappy little place that was once dedicated by John McLaren and the RPD Commission as the Experimental Grounds for birds and wildlife. RPD claims it has no records of that, but it is well noted in some of our earliest Gulls.
Good birding,Dan Murphy
