returns of the day

The Tricolored Heron was back this morning. It came in as I was standing on the edge of the pond; it seemed to come up from the marsh and it actually flew straight towards me, landing in the middle of the pond. Among the pond denizens, only the Willet is so tame that it will fly at you rather than away from you when your figure looms up across its field of vision.

Yes, the Willet was there too. Also a Green Heron -- much more shy than the other waders -- was hiding in the trees at the edge of the marsh; it was, I think, being harassed by crows. The crows were very nervous this morning and one of them in particular was raising up quite a racket. Curious to see what the trouble was, I tracked her down only to realize that he (or she) was in fact tracking me! I was the intruder she was yelling about. The explanation was almost certainly that there was a newly fledged young crow in the area and I realized that I could make out its calls quite clearly.

It's often said that the calls of a young crow and the calls of the Fish Crow can be confused but when you hear them at the same time, as I did this morning, the differences are quite clear. The Fish Crow calls were isolated repeated nasal notes in a steady pattern while the young crow's calls were much more random and varied.

Among the morning's return visitors: Great Crested Flycatcher and Pine Warbler, two species that have, I believe, a wide circular range that includes our woodlands. Also Red-eyed Vireo and Common Yellowthroat. The Brown Thrasher, who sang all yesterday afternoon, did not reappear.

A House Finch sings regularly at the foot of Weesuck Avenue (just off our property); this is a species that was formerly much more common but was apparently decimated by an epidemic; it may now be making a comeback. And, though I don't like to admit it, the dreaded Cowbird -- a species that parasitizes other birds by laying its eggs in their nest (with the result that they raise Cowbirds rather than their own young) -- is also in the neighborhood.

Two more (and better) pictures of the Big-leaf Magnolia, Magnolia macrophylla, in bloom.
