Ohmigosh It's Happened! A Blue Grosbeak on the Tuolumne River Trail!
The other time it was about playing the odds. It's spring, and flycatcher species are arriving in the region, so I'm paying more attention to the particular trees and branches where I've seen them in years past, and thus I discovered an Olive-sided Flycatcher on the trail a day or two ago.
But today was strange because I've never seen a Blue Grosbeak (Passerina caerulea) on the Tuolumne River Parkway Trail. Not once in the four years that I've been watching for them. I've seen them eight miles upstream at Robert's Ferry, and I've seen them ten miles downstream, but no closer than that. It stands to reason that they would come through the area, but I've just not had the ability to pick them out up until now.
The Blue Grosbeak is a tropical migrant that spends winters in Central America and Mexico. They come north to breed, and our valley is near the northern edge of their range (although their range is expanding). It is one of the prettiest birds I've ever come across, and it was such a thrill to finally see one in my "backyard".
