We weren’t even out of our campervan before California Thrashers, Gambel’s Quail and Western Scrub-Jays came by to (maybe) check us out. Colorful lizards sunned themselves in the cactus garden. Unlike the movie, it would be a good day at Black Rock.

A few years ago we broke this trip into two parts: Saturday afternoon at Black Rock Campground; Sunday morning at Morongo Valley Preserve & adjacent Covington Park. Late afternoon, after the heat of the day, when birds begin rousing themselves for a final burst of feeding, is a good time for Black Rock. Many birders had already taken to moteling Saturday night in Yucca Valley, close to the campground five miles south into northwestern Joshua Tree Nat. Park. The best time to see Piñon Jays is shortly before sunset, when they fly up and downslope above the campground. Other birds are always around the campground, but – as do most birds everywhere – they make themselves scarce mid-day.

We found most of the Black Rock specialties: Gambel’s Quail came to water drips and called from the Joshua Treetops, the increasingly more common White-winged Dove, several hummingbirds worked the bushes and ephemeral flowers, Ladderbacked Woodpeckers drilled the Joshuas, the aforementioned Piñon Jay, Verdin with faces the color of yellow mesquite flowers, the squat-jumping Rock Wren and the cranky Cactus Wren, desert early-nesting Phainopeplas, the Black-throated Sparrow who never drinks water, and the lovely-to-see-and-hear Scott’s Oriole. Perhaps the most uncommon sightings were several Chuckwalla lizards warming on rock tops, and a large

us missed. We then went off to dinner at La Casita in Yucca Valley, a good Mexican restaurant. Those of us camping returned, stuffed to the gills, to Black Rock and waited for the wind to rise. Infamous for its winds – we call it Windy Ridge – people have seen their tents sail away into yucca-strewn gullies, or been rocked to sleep – or to terror – by a wind-wobbled campervan.

Next morning, on the way from our Black Rock campsite to Morongo Valley, we spotted two Roadrunners, one road-crossing as we coasted down the long road back to the highway, and one crossing the highway itself, right in the middle of town. I almost forgot: Lillian and I witnessed a 6:05am flyover of 60-100 Piñon Jays, heading downcanyon directly above our campsite, each one calling in their peculiar quail-like purr.

Morongo Valley Preserve was moderately birdy and – for a change – neither windy nor unbearably hot. Warblers were few: we did see six of the eleven western warbler species, but

95% of them were Wilson’s Warblers. Summer Tanagers have apparently already paired up; we first spotted them whizzing back and forth, and later at the seed feeder by the warden’s house. Brown-crested Flycatchers were very vocal, as were Yellow-breasted Chats, and we heard them singing and calling over and over before we finally spotted either species. At least one pair of Vermillion Flycatcher were in Covington Park, and we saw a female sitting on her nest near the tennis court, her mate

busily bringing her flies. Nearby, birds, including Lawrence’s Goldfinches, were coming to the small water drip someone had set up. White-winged Doves were frequently seen; a few years back we had to diligently search for this species, often missing it, but now they seem widespread. At the seed feeders we could admire their blue orbital ring.

Morongo Valley is one of the few areas where the ranges of the Nuttall’s and Ladderbacked Woodpeckers overlap, and they do interbreed. Of the photos taken, none are clearly one or the other species. Check the three photos for some of the annoying details.

All told, we had 66 species in two days, down from 2013’s 76 species (see list below). A lot depends on which winds the birds encounter as they move north from the brushy shore of the Salton Sea. A good tail wind and they sail right on by, high over the hills. A stiff head wind like the screamers that come through San Gorgonio Pass, and they are forced to stay low and slow, moving up through Big Morongo Canyon to rest and refuel at the Preserve.

Brown-crested Flycatcher (D. Erwin 5/3/15 Morongo)

Ash-throated and Brown-crested Flycatchers both nest at the preserve. Very similar in appearance, even the thinner bill of the Ash-throated can be mistaken by some (moi!) for the chunkier bill of the Brown-crested. Fortunately, the latter bird has a much more liquid Whit! call and rolly song than the former. If you’re lucky, you’ll see one sing. [Added Note: The fact that this photo was captioned “Ash-throated Flycatcher” in the original email demonstrates how easily they’re confused.]   [Chuck Almdale]

Many thanks to Dennis Erwin and Roxie Seidner for all the great photographs!
