Since bird numbers continue to dwindle as their habitats are destroyed, it is my opinion that more birds get concentrated in remaining habitats. Hence the consentration of songs.

As caring people continue to upgrade native plantings in local parks, and their yards, more birds will be drawn to these bird friendly oasis. If enough people protect remaining habitat, and help improve local their habitats, perhaps the birds will be able to survive.

On Friday I visited the 500 Area in Discovery Park, which is the section including and north of the south parking lot. In my many years there I have never heard such a "wall" of song. Western Tanagers, Black-headed Grosbeaks and Warbling Vireos sang from every direction, in their dozens it seemed. With Juncos and other sparrow and warbler species thrown in it was an unforgettable sound. One must believe that most of these birds were part of a migratory fallout. And yet in recent years my opinion is that these species of tanagers and grosbeaks have become more common in the park perhaps because of the seral stage of mixed forest now growing.

The park already had a small wave of this species in early May. In most Junes, Cassin's is an uncommon breeding species. Also in early May was a wave of about a dozen Purple Finches, singing the warbling song, but in a slightly abbreviated version. Each bird found visually proved to be in immature/female plumage. I guess all I am saying is that sometimes birdsong is hard to interpret and that one needs several pieces of evidence before breeding can be assumed
