Sunol Regional Wilderness - 5/10/10

Eric Pilotte

I made a visit to the Sunol Regional Wilderness this morning that included a quick hike near the visitor's center (pre-rain) and a drive up Welch Creek Road in the drizzle. Other than Swainson's Thrushes, migrants weren't very plentiful. However, the breeding birds of the area were singing in all their glory. Highlights included:
- 16 Swainson's Thrushes (10 of these were scattered along the pavement of Welch Creek Road)
- 4 Cassin's Vireos
- 5 Hairy Woodpeckers at various locations making lots of noise
- 4 Lazuli Buntings
- Only 2 Western Tanagers :(
- 6 Acorn Woodpeckers standing on the pavement
- No Wood Ducks near the footbridge of the visitor center, but 1 female Common Merganser there calling repeatedly (young nearby?)
