Kleptoparasites follow Brown Pelicans
October 19, 2019
Early each morning from the top of Lighthouse Hill, Point Blue biologists count Brown Pelicans roosting on the South Farallon Islands before they leave to forage for the day. For the past month, pelican counts have been consistently high, with numbers frequently topping 1000 individuals. On October 17th, 3301 pelicans were observed, the highest number
Calm winds bring birds to the Farallones
October 16, 2019
On October 15th, the anemometer on the island weather station came to a halt under a low cloud ceiling; low winds and extensive cloud cover create ideal conditions for attracting migrant birds to the island.
Migrant wave
October 10, 2019
Today brought light winds, great visibility, and lots of new migrants including this gorgeous golden-crowned kinglet. Check out our ebird list to see what else we saw today (http://ebird.org/hotspot/L329116).
Farallonathon 2019!
October 9, 2019
From September 27 to October 3, the fall crew conducted the 28th annual Farallonathon, the Southeast Farallon Island rendition of Point Blue’s annual Bird-a-thon fundraiser. Points are awarded for each unique species of bird, marine mammal, bat, fish, salamander, dragonfly and butterfly throughout the week. Supporters are encouraged to pledge a donation per point earned during the Farallonathon to help support our research and conservation work on the Farallones. Or, you can simply make a donation in a fixed dollar amount. Every bit helps. This year the Farallonathon resulted in a total of 128 points and includes highlights such as Painted Bunting and Yellow-green Vireo.

A slow, yet surprising September
September 29, 2019
Despite low overall numbers for the fall migration so far, September has brought a nice assortment of island rarities.
Tag! Fur seals are it on the Farallones
September 23, 2019
Starting in 2017, Point Blue biologists began working with partners at NOAA’s Marine Mammal Lab in Seattle and The Marine Mammal Center in Sausalito to deploy flipper tags on northern fur seal pups at the Farallones. By tagging pups with unique numbered identification tags, we are able to follow them throughout their lives and learn about pup survival at this colony, recruitment of young into the future breeding population, and movement of individuals between the Farallon rookery and other fur seal rookeries.
Fall migration isn’t just for the birds!
September 9, 2019
During the fall months, humpback whales begin their long migration from cold, food-rich waters in the north to the warm waters of the southern calving grounds. We’ve recently seen a sudden influx of humpbacks around the island as a large wave of migrants coming down from the north are drawn in close to the island by large schools of bait fish like anchovies.
The fall crew arrives (and so do the migrants!)
August 20, 2019
Mid-August is an exciting time of turnover on Southeast Farallon Island, with the summer season drawing to a close, and the fall season just starting to heat up. The arrival of the fall crew on Saturday coincided perfectly with a sudden influx of migrant songbirds. Highlight species thus far have included a vagrant Northern Waterthrush and more common western migrants such as Hermit Warblers, Yellow Warblers, Townsend’s Warblers, a Willow Flycatcher, and a Lark Sparrow.
Netting For Fish
July 27, 2019
By Miles Scheuering It is the peak of the chick-rearing period for rhinoceros auklets on Southeast Farallon Island, which means every night the adults return to their burrows with bill-loads of fish for their chicks. As part of a long-term monitoring study of their diet, we use mist nets to capture adults and collect
The Secret Lives of Murres
July 18, 2019
By San Jose State University graduate student and former Point Blue intern Sean Gee. Common murres are the most populous seabird species breeding on the Farallones, and one of the most abundant seabirds in the north Pacific. Point Blue Conservation Science has been collecting data on the population size, breeding biology, and chick diet
