I came back
from my sixth visit to Baja California Sur earlier this week. This was the
third time leading the regular WINGS tour here, with other trips being my first
scouting trip and two private tours. It was a delightful tour – short, full of
birds, beautiful scenery, and a really good group. We had six and a half days
in the field, though it seemed more like a long weekend, it went by so fast.
Our first morning at San José del Cabo began with this sunrise from in front of
our hotel.
We birded
for about three hours at the Estero San José, one of the birdiest places in all
of southern Baja, thanks to the ponds, marshes, and oasis vegetation. We pretty
quickly found the endemic Belding’s Yellowthroat, getting good comparisons with
the more common wintering Common Yellowthroats. Out at the beach we enjoyed
watching these Magnificent Frigatebirds coming in for a morning bath, which
they do only in flight.
This was one
of two Palm Warblers wintering where the marsh meets the beach and some weedy
patches of morning glory create the perfect structure for this mild rarity.
Almost back
to the car, I spotted this Gray Thrasher preening low in a bush, our second
endemic species. Unlike all other endemic taxa, which are pretty much
restricted to the southern tip of the peninsula, the Gray Thrasher is found
north almost up to the US border.
Later
morning we visited the inland oasis-like wash of Miraflores. Hooded Orioles are
very common winter birds here.
This area
hosts a sizeable and rather isolated population of Thick-billed Kingbirds, and
we managed to get good views of one.
Xantus's
Hummingbird was our third (and final) endemic species, all in the pocket before
lunch. This is a female.
I recognized
this Rhynchosia precatoria, Rosary
Snoutbean (called Bird-eye Bead in my Baja California Plants book) from one of
my trips to Rock Corral Canyon in SE Arizona, the only place in the United
States where it occurs naturally.
After a
delicious lunch of fresh seafood tacos (I had the lobster), we drove to a
remote headland on the Gulf of California called Punta Arena. In the desert
scrub along the way we flushed many Northern Mockingbirds and California
Scrub-Jays, then paused just long enough to get good photos of this Loggerhead
Shrike.
We strolled
along the beach casually, finally catching up with the group of over a dozen
Snowy Plovers that I’ve seen here before, but also noting a Least Tern hunting
just beyond the surf (apparently quite rare in the winter here), as well was
Munk’s Devil Rays leaping out of the water.
There were
dozens of shells on this remote beach, and it was impossible to resist picking
them up. I rarely have the urge to take things like this home to clutter my
shelves but am glad I decided to take a photo. My tour participants helped
select some diversity of sizes and
colors.
On our way
out, our van got mired in the sand where we had earlier driven without any
problem. I shouldn’t have slowed down, but on the way here it didn’t seem a
problem. The Nissan Urvan’s weak motor and disproportionately small tires are
not well suited for any loose substrate, I learned. I jogged nearly 2 miles
back to the beach to enlist the help of the very friendly fishermen (visible
behind us on the beach in the photo above) who helped dig the sand away from
the wheels and push the van out.
Thanks Rich for the great information here! I am working on an October trip/pelagic from Guaymas to Mulege with some ladies. There aren't a lot of reports from that area so I thought it would be fun to check out. There is a mission in the Baja area called Santa Roslia that has Riparian area around it.....will be checking for the Belding's Yellowthroat and Xantus there. And maybe a Gray Thrasher will show up. Should be interesting. I know most people head to La Paz but I suspect there is some good habitat that some exploring around the Mulege area. Have a great weekend! Chris
ReplyDeleteThat sounds like a great itinerary. I wish I could join you! Let me know if you have any questions on spots in the Cape Region; I've never been north of Ciudad Constitución/Puerto San Carlos. It's a good season for vagrants when you'll be there, so keep an eye out for anything.
