Happy Halloween!  Moderate northwest winds, low visibility, some rain, and fog conspired to make our Halloween a relatively quite one.  The sole new arrivals were a pair of Clay-colored Sparrows. Holidays on the island are always a little different.  For example, this Halloween, no one dressed up, and we had zero kids trick or treating.  […]

The weather looked promising today with overcast skies and light east winds, but there were very few arrivals.  Two birds of interest were the two Red-breasted Mergansers that were found in Mirounga Bay.  The mean arrival date for this species is 24-Nov so these two were on the early side.  Another arrival was of a juvenile tundrius Peregrine […]

Bats on Southeast Farallon Island

The morning of October 14, 1987 on Southeast Farallon Island was like something out of a bat biologists’ dream. To the biologists that lived on the island, it was just one heck of a “bat day”. Although hoary bats (Lasiurus cinereus) had consistently appeared on the island each fall since at least the mid 1960’s, […]

Today’s weather was cloudy, with low visibility and light northwest winds. Despite the weather conditions, we had the arrival of a couple exciting birds. During the morning area search a group of five American Pipits were seen foraging on the marine terrace. Upon closer inspection, one of the pipits turned out to be of the […]

Moderate northwest winds and solid cloud cover today. There weren’t a whole lot of birds around today, but we managed to find a few interesting things. In the morning we had a nice flight of shearwaters, dominated by Buller’s, followed by Pink-footeds and Sooties. Other finds were Surf Scoter, Ring-billed Gull and Thayer’s Gull. Thayer’s […]

The winds switched around to the northwest and remained relatively light. We had decent visibility and cloud cover. The geese (Greater White-fronted and Cackling) that arrived yesterday were still around today. Wilson’s Snipe and Band-tailed Pigeon were new today, although the snipe didn’t make it the whole day since it was “taken out” by one […]

As always the internet connection has been very uncooperative, so we’ll just try to post a large block of lists now that it’s working. Over the past week the winds have generally been out of the northwest with varying degrees of cloud cover. There have been a smattering of new arrivals including Swamp Sparrow, Grasshopper […]

A Seabird guy in a Songbird season

There are three main “seasons” on the Farallones. These are not defined by weather or hours of daylight, but rather by the species of animals that inhabit the island. December to early March is “the elephant seal season” when research activities center on the breeding biology of the Northern Elephant Seal. Mid-March through August is […]

Light and variable winds with cloud cover overnight gave us hope for a wave day, but by morning we were in some pretty heavy fog. Since any migrating birds would have a hard time finding the island, we ended up only seeing a few new arrivals (flock of Cackling Geese flying over, Cassin’s Vireo, and […]
