SPECIES SEEN
From 3/24/2008 to 3/30/2008 ~ 68 seen
The number of species recorded on the Anza Trail this week is down, but I am sure it is more a function of my spending less time on the trail than the variety of species actually declining. Between the Tuesday walk (thanks to George Freeland for providing me the list) and my observations, there were 68 species. Six additional species were recorded by other birders.
In general, the number of species of flycatchers and vireos is increasing, though the number of individuals remains small. In contrast, the number of species of sparrows remains high, but the number of individuals declined markedly.
For example, White-crowned Sparrows, normally everywhere at this time of year, are hard to find. One highlight of the week was a MacGillivray's Warbler 
found a couple of hundred yards south of the second foot-bridge south of Clark's Crossing. It is the first report this spring of a MacGillivray's anywhere in the region.
Another highlight was a first of season Swainson's Hawk seen on the Tuesday walk. 
Finally, I saw Bullock's Oriole on the trail, but have no recollection of where. If you bird by ear, Bell's Vireos and Lucy's Warblers are singing on most sections of the trail.
Birds seen by other birders and not on this list were Painted Redstart (south of Bridge Rd.), Louisana Waterthrush (same area), Sora (borrow pit), Zone-tailed Hawk, Virginia Warbler, and Gray hawk. ~ Jim Karp
