The One that Got Away (Little Bunting)

By Luke Musher

Today was an unexpectedly good day for us on Southeast Farallon Island.  We had a Rusty Blackbird, which is a CBRC species and a Summer Tanager, which is also a rather good bird for the island.
Rusty Blackbird, Southeast Farallon Island, CA.
However, it was also an unexpectedly horrible day.  We saw a Little Bunting.  I know what you are thinking.  "That doesn't sound so bad.  Little Bunting has only occurred in North America outside of Alaska two other times, once of which was on the very island you are on now.  You guys found an extremely rare bird."  No; it was horrible because nobody photographed it.  The bird will almost certainly not be accepted by the CBRC without a photograph, and there is little we can do about it.
At least we can prove that this bird exists.
Jim Tietz initially found the bird and radioed to us to bring our cameras immediately.  When we got there the bird had just flown.  Jim described the bird to us, small emperezid sparrow with a lot of chestnut on the face, light streaking on the underparts, white outer tail feathers, eye ring, and call a faint tsip.  Then we searched a little more, but were unable to relocate the bird.  I kept looking and found a Pine Siskin with another bird.  I couldn't see the bird well, but I distinctly heard a call just like Jim had described so I kept on it.  The bird then flew straight at me.  I could clearly see the chestnut face, eye ring and white outer tail feathers, and the call matched Jims description.  I ran after the bird while radioing the rest of the crew.  The bird then flew back over my head towards where it came from and was never seen again. I just listened to several recordings of the their calls from asia, and was pleased to see that most of the recordings matched what I heard.

I am hopeful that the bird is still on the island and that we will see it tomorrow (unlikely).


Here's a link to our ebird checklist today including Jim's description of the bunting:

Farallonia's Common and Scarce

By Luke Musher
HY Anna's Hummingbird, a common bird on the Farallons.
Since I first arrived, I have found it incredibly interesting how some species that are fairly abundant just 30 miles east on the mainland can be incredibly rare, and are thus highly coveted by us Faralisters here in Farallonia.  Then there are birds that are much more likely to turn up here than on the mainland.  For example we get far more Least Flycatchers, an eastern vagrant, than Dusky or Hammond's Flycatchers, which are relatively common species in the west.  We recently had two Farallon megas, Common Goldeneye and Cooper's Hawk that are doubtfully any birder's idea of chase birds.  However, birders who spend time on the Farallons take their island lists very seriously, so when I called out the goldeneye over the radio, the others came sprinting to me as if it were an Arctic Warbler (not surprisingly also induced a rapid and shamefully twitchy response).
NOT the Loch Ness Monster, but the 20th Island record and 6th Fall record of Common Goldeneye for Southeast Farallon Island.  Nearly all records are in winter.

Despite the fact that the birding has been slow due to various amounts of wind and/or fog, we've had a a trickle of arrivals over the past few weeks, including new Grasshopper Sparrow, Lapland Longspur, Short-eared Owls (almost daily), Rough-legged Hawk, Blackburnian Warbler (a good vagrant anytime, but especially this late in the season), and Surf Scoters to name a few. 
Lapland Longspur, the most likely species of longspur here, but still a relatively uncommon bird.
Short-eared Owl, a common species but an outstanding bird every time.
We have butterflies too, like this west coast lady....
...and this painted lady.
We haven't seen many Pigeon Guillemots lately, but this individual, Hermen, has been here since the breeding season, and is finally molting in a much-needed new set of remiges.
One of my favorite recent birds was a Horned Puffin yesterday (pow! that's a lifer) that was spotted while we were operating the crane to bring the boat on shore.  Ryan DiGaudio, Nora Livingston, Maggie Spilatro and I all basically spotted the bird at exactly the same time and realized it wasn't a Tufted Puffin, which breed on the island and would be far more likely, but a Horned.  Jim Tietz got this as an island bird while still waiting on the boat he was arriving on.  Note the white underparts, pinched base of the bill, and obvious paleness in the face–much different than any Tufted Puffin.  What a BAMF.
Eh not the best photo ever, but a great bird anyway.  Horned Puffin just chillin'.  One of less than 30 records for the island, 8th fall record.  This bird is far more likely in Spring, but rare any time, and scarce in any part of coastal California.

Mega: Arctic Warbler


I woke up this morning to fog and south winds, and soon after, the fog lifted, and the wave began.  We banded 42 Red-breasted Nuthatches today, and 70 birds all together.  We saw a total of 69 species.  Oh and did I mention?  We had an Arctic Warbler hit one of our mist nets.  This mega rarity represents the 2nd record for the island and 8th for California.  Still, we all just found out about the Common Cuckoo in Santa Cruz, CA...that bird wins.
