The Fall Crew arrived on Southeast Farallon Island on 16 August to find two adult Blue-footed Boobies, an adult Brown Booby, and the continuing adult Northern Gannet, all on Sugarloaf and right above where we conducted the switchover with the Seabird Crew. Three species of birds from the family Sulidae at one location in California is highly unusual, since none of these species breed in the state. Thankfully, this was to be an auspicious start to a bountiful August and September.

Over the past several years, the weather during late summer (Aug-Sep) has been mostly foggy or windy, with just occasional light winds and high overcast days that are conducive to allowing migrants to the find the island. This year, however, was quite the opposite, with fog noted for brief periods on only 7 days, and winds stronger than 10 knots on only 10 days, and never stronger than 20 knots.

Our first surprise of the fall occurred on just our third day on the island, when an adult male Painted Bunting showed up outside of our kitchen window during breakfast time. Although we have seen several Painted Buntings over the past decade, this is the first adult male that has ever showed up on the island. Numbers of western migrants began increasing a few days later, including Baird’s and Least Sandpipers, Yellow, Hermit, Wilson’s, MacGillivray’s, and Black-throated Gray Warblers, Chipping and Savannah Sparrows, and Lazuli Buntings. A few highlights from late August included our 12th record of Virginia Rail, three Least Flycatchers, our 17^th fall record of Gray Flycatcher, our 51^st record of Blue-gray Gnatcatcher, 74^threcord of White-tailed Kite, a Northern Waterthrush, an American Redstart, a Baltimore Oriole, and an Orchard Oriole.

The weather throughout early September was even more conducive to migration – high overcast skies and very light winds nearly every day – resulted in still greater numbers and more diversity. Yellow Warblers and Townsend’s Warblers were most abundant, especially compared to recent years, with 54 and 40 arrivals respectively. Highlights from this period included our 36^th record of Green Heron, a flock of four White-faced Ibis (just the 3^rd occurrence of this species at the Farallones), our 28^threcord of White-winged Dove, our 46^th Chimney Swift, our 22^ndand 23^rd Acorn Woodpeckers, possibly our 4^th Alder Flycatcher (DNA analysis will be required to separate it from eastern Willow Flycatcher – until then, it is considered a Traill’s Flycatcher), our 11^th Yellow-bellied Flycatcher, 69^th Mourning Warbler, 77^th Bay-breasted Warbler, 70^th Prairie Warbler, and an adult male Indigo Bunting (rare plumage for fall). A short lull in bird migration occurred during mid-month. This may have been due to the excellent visibility, which allows birds to see the mainland, where food and shelter are more plentiful.
