Adult plumage? I’m at Battery East and will report promptly if it comes in view. Brian Fitch

Just after 7 AM this morning, a Common Tern flew by the terrace at the Sutro Baths, heading into the Gate. It looked like a different bird than the one Joachim found last week on the beach. Though it

I've never witnessed adult cowbirds feeding young, but have often seen young birds feeding themselves in the company of adults of their own species. I've wondered how many days or weeks pass before ju

After spending some days in saner parts of the state, I hit the city today, with a multi-hour seawatch and a check on North Lake. The diffuse fog haze made distant viewing tough, and all of the intere

This is fascinating on multiple fronts. Nico invokes Kroodsma last night, which led me to pull Kroodsma's book off the shelf to give it another look, and then Greg passes along some live Kroodsma, off

This is striking a deeper issue for me, so I'll try again. If this is a Bewick's Wren, then it's not likely a migrant, and it could be out there trilling away in McLaren, if only we knew where to list

During our morning neighborhood walk, my wife and I watched an Ash-throated Flycatcher fly nearly the length of the park heading east and out of sight. A first for this site, and so close to making it

Here are a few findings from some simple on-line research over the past few hours. Anhinga species (4 world wide), do not seem to be kept regularly in zoos, though there was one in recent years at San

Just received word that escaped African Darters have been seen in the south state in the past. I'll leave it to others to consider the likelihood of one making its way up here, or to discover whether

Around 10:30 this morning, Aaron Maizlish and I were standing at the north end of the Fort Scott ball field discussing how to judge the odd weather in regards to where to search for birds. The wind wa

I may be ruining what reputation I have , but I believe we just had an Anhinga soaring south of Ft Scott, quite distant, but showing the classic shape from beneath and then in profile as it broke its

A very strange flight profile just headed sw from ft scottt Anhinga like soaring Look up Brian Fitch

Nothing to match the magnitude of yesterday's six (6!) rare species newly found in SF, but on our neighborhood walk this morning my wife and I saw or heard singles of Olive-sided Flycatcher, Ash-throa

A northeast vector will take them diagonally across the entire city. So if you can, look up and track these beauties and let the rest of us know about it pronto. This is the best possible use of cell
