Watering My Dove

No, that's not some perverse euphemism. I really did just that. This Mourning Dove is nesting on a potted plant that my landlord installed on the ouside of my house, facing the patio that separates our houses. The bird sits amazingly still, and while I was spraying the plants, I forgot about her and doused her and her eggs well. She flushed, startling me. But now she has two fat chicks and tolerates amazingly close approach. (The bird in this photo is the male, with a contrastingly gray crown and nape.)

Birds and Natural History of Baja California Sur


View Larger Map
I've just returned from a scouting trip to the Cape Region of Baja California, from March 1-6. I was joined by Dylan (who had joined me in NY too) and Keith Kamper. The two coincidentally had been planning a trip there in the same time frame.


We had similar goals of seeing all the endemic birds. Seeing the three that the AOU currently considers to be full species is very straightforward and can be done in just a couple hours from either airport (La Paz or Los Cabos), with some luck.

The Belding's Yellowthroat is found in marshy spots (Dylan's photo).





















The Gray Thrasher is found in desert and thickets in tropical deciduous forest.







































And the Xantus's Hummingbird is found pretty much everywhere, requiring flowers for feeding, of course. The flower is Tree Ocotillo, Fouquieria digueti.





















But there are a whole slough of endemic forms currently considered subspecies, some of which will certainly be classified as species once more information (analysis of voice, genetics, etc.) becomes available. Most of these are very isolated from other subspecies and occur in the higher elevations of the Sierra de la Laguna, in oak and pine-oak. There is one dirt road that gets into some oak at an elevation of about 2400 feet, about 14 miles from the highway. The cottonwood-lined wash and oak - palm slopes gave the area a very unique feel.

















Here we caught up with the endemic form of the American Robin, known as San Lucan Robin (Dylan's photo).

















And the dark-eyed subspecies of Acorn Woodpecker.













"Cape" Pygmy-Owl, currently still considered a subspecies of Northern Pygmy-Owl, though its calls are higher-pitched and faster-paced.

















The flowers and lizards here were terrific, even some cool butterflies.













Pacific Tree Frog











Orange Owl-butterfly (Opsiphanes boiduvallii). It turns out there is only one specimen record and a couple sight records of this species from Baja California. It is possibly an introduced population, with eggs, larvae or pupae riding in on ornamental palms.

















Vivid Dancer







San Lucan Rock Lizard
















Black-tailed Brush-Lizard














The rarest bird of the trip, and perhaps our only true vagrant was this White-eyed Vireo (Dylan's photo). This represents the first documented record for Baja California.















There are several other endemic subspecies, the rest of which were accessible only by hiking into the highlands. On our last full day, Dylan and I did this. Fourteen miles round-trip and an elevation gain of 4300 feet. We covered it in 9 hours and 15 minutes. Sadly, Keith twisted his ankle a couple days before and wisely chose to sit it out. Dylan was wiped out at the end (look at the expression on his face on the home stretch here), and I was glad I had been doing lunges, squats and sprints as part of my workout.

















Our main goal was "Baird's" Yellow-eyed Junco, which is really nothing like a Yellow-eyed Junco, except that it has yellow eyes. Color, shape, and voice are wrong. (Dylan's photo.)















It was a great hike though, and the habitat up at 5800 is lovely. We made it as far as the first endemic Laguna Pines




























The wildflowers were nice. Norm Douglas of North Carolina State University informed me that this is Commicarpus brandegeei, formerly placed in the genus Boerhavia. His genetic research showed that the two genera are not all that closely related.

















This is Belding's Beargrass, looking more like the tree-like Beaucarnea.

















A Eupetorium.

















I'm not sure what this is (probably family Acanthaceae), but the hummers like it.

















The endemic subspecies of Rufous-crowned Sparrow (Dylan's photo).














We also added the endemic Hutton's Vireo, Bushtit, and White-breasted Nuthatch on this hike.

I also had the added goals of learning all the potential birding spots, getting hotel and transportation information, and doing a boat trip to Espiritu Santo island to determine if it were worth including in a tour itinerary. We saw precious few seabirds on the boat ride around the island.























But we were able to get off at one point and explore for about an hour.












The San Lucan Rock Lizards were bluer overall, though said to be the same species as on the mainland.

















But the Antelope Squirrel is endemic to the island.














Yellow-footed Gulls are everywhere.















At the beach where we landed was a tour group which spent the day kayaking and snorkeling.













In checking out hotels, we found a couple very nice places, such as Punta Colorada.













Here are just a few more photos from around the peninsula.

Murphy's Metalmark

















Probably a Giant Hairy Scorpion, but I haven't gone to the library to look it up.















The Cactus Wrens here look and sound quite different from the ones in Arizona.

















California Dancer









'Giant' Mexican Metalmark

















Franklin's Gull at the La Paz sewage ponds, a rarity here.

















Zebra-tailed Lizard, though the ones here don't have a banded tail (Dylan's photo).













The necessary goof shot in Todos Santos. Yes, this is the hotel of the Eagles' song.













A gorgeous oasis south of Todos Santos, Playa San Pedrito.













Final tally:
178 species of birds
30 species of butterflies
10 species of herps
8 species of mammals

New England, New York and Long Island in Winter

It was all Dylan's idea, to go to Montauk, at the eastern tip of Long Island to see the two vagrant geese wintering there: Barnacle Goose and Pink-footed Goose. With some logistical juggling (frequent flier flights on an open-jaw ticket, bus rides, and contacting a bunch of people to see if my friends were available to host us), we took the plunge. It was a fabulous trip.

I went a couple days before Dylan and spent an entire day with my oldest niece Jennifer on Valentine's Day. It got to know my great nephew, Ashlar and met Jenn's partner Vicki for the first time. Next time I will have to make it a longer visit and not when there is 3 feet of snow on the ground.

Then I was off to New York on the Fung Wah bus from Boston to Manhattan. I met up with Doug Futuyma and that evening was treated to a great performance of Verdi's Otelo at the Metropolitan Opera. Dylan arrived in the meantime, meeeting up with us at Doug's pied-a-terre in the Upper West Side.


The next morning, we met up wth Olaf Soltau and made a day of birding our way east on Long Island. Doug was a great tour guide, making sure we covered all the spots likely to have any rarities, and netting Dylan two lifers, Purple Sandpiper and Iceland Gull. Here's the Iceland Gull (sandwiched between Herring Gulls) on our last day.















After netting the Barnacle Goose, Doug and Olaf dropped us off with Anthony, Philip, and Michael. Anthony had agreed to house us and the rest of the crew at his weekend cottage in East Hampton. We spent the rest of the weekend birding the eastern end of the island, with only the Pink-footed Goose remaining. Luckily, it showed up Sunday morning with no trouble. Huge rafts of scoters and eiders at Montauk Point were a highlight as were a couple "Ipswich" Savannah Sparrows.

The other highlight of the weekend was the fun time had back at the cottage, with wonderful food prepared by the non-birding spouses (Judi, Galen, and Justin). A weekend to cherish.
