FARALLONATHON 2011
October 8, 2011
It’s Bird-A-Thon season at PRBO – our biggest annual fundraiser. On the Farallon Islands, we do things a little differently (not surprising)! Instead of counting just species of birds on a single day, we count all of the animals we encounter including birds, fish, marine mammals, insects, and any other wildlife we find over an
Fog – too much or too little of a good thing
October 7, 2011
The coastal marine layer off California (AKA, advection fog) is formed when moist air blows horizontally over the cold water of the California Current. The cold air above the water forces the moisture to condense into visible water droplets suspended in the air which obscure visibility when the cloud ceiling approaches ground or sea level.

Spring and Summer on the Farallon Islands is abundant with breeding seabirds (13 species, to be exact), but Western Gulls are one of my favorites to observe. One of my tasks on the island requires me to monitor a small plot of breeding Western Gulls. There are four gull plots on the island, each of

Sefi has shorebirds too!
July 10, 2011
On Southeast Farallon Island there are 12 different breeding species of seabirds, many of which have been profiled on this blog. However, there is one species that has not been showcased yet, the Black Oystercatcher. Oystercatchers are the only breeding shorebird on the Farallones, nesting primarily along the rocky margin of the island just above
