Birding the Kill Bill Superbloom

Superbloom at dawn – Luke Tiller

This Sunday David Bell and I ventured out into the wilds of Northeast LA County to check out what was happening with this years superbloom. This year has been an incredible one for wildflowers across the Southwest.  As well as the flowers, I was intrigued as to what might turn up there bird wise. Adding to the potential interest was the fact that Jonathan Feenstra had found what appears to be Los Angeles County’s first record of Black-tailed Gnatcatcher in over eighty years just a stones throw away on Edward’s Airforce Base, on a section that isn’t open to the public.

The thing I like about birding with David is that he’s always up for trying somewhere different rather than chasing birds or hitting the same old birding sites. It was for this reason that we found ourselves stopping at dawn amid a sea of yellow desert wildflowers at the Kill Bill Church (more here) in Hi Vista to see what might have stopped off in this one horse town during migration. It actually turned out to be a fairly productive stop with highlights including specialist local breeders like Black-throated Sparrow as well as a couple of out of place migrants including a beautiful Yellow-headed Blackbird.

We then worked our way north on East 200th Street past the Phacelia Wildlife Sanctuary to explore the very northern edge of the county, stopping only when the road would take us no further. Here at the end of the line, a gate blocked our entrance to Edward’s Airforce Base. It was a surprisingly productive end of the line however with singing Le Conte’s Thrasher (or LeConte’s Thrasher depending on what the AOS decide) and five species of sparrows that included three real beauties: Bell’s, Brewer’s and Black-throated Sparrow.

We were soon stumbling on more birds as we worked our way through the Creosote Bush and Joshua Tree covered landscape. In my experience this habitat often seems to be pretty birdless, but today we kept stumbling upon little flocks of White-crowned Sparrows and in among them other birds would appear. Some expected, like the Rock Wrens and Verdins, some much less so like the migrants that seemed to have joined in these little roving flocks: Chipping Sparrow, Ruby-crowned Kinglet and House Wren. It seemed like almost every bird freaked out the local eBird filters however, highlighting how little this area gets birded.

Of course usually this area is pretty barren desert, but this year there are plenty of flowers for these birds to enjoy, and looking carefully at my photos from the day, plenty of accompanying bugs. With the superbloom it makes me wonder how the usual desert migrant traps will fair this Spring. With the desert somewhat greener than usual I wonder if those places will be less of a draw for wandering birds or whether the abundance of growth in the desert may somehow end up helping waifs and strays survive and similar or greater numbers will find their way to those weird little desert oases? It will be interesting to find out.

As well as a fairly constant turnover of birds there was much else to enjoy including lots of neat flowers. Almost everywhere you looked was a carpet of yellow flowers mainly formed by millions upon millions of little California Goldfields (Lasthenia californica) but there were other pretty ones in among them including the purple Phacelia that the nearby wildlife sanctuary is named for. You can find LA County Parks and Wildlife Refuges using their parks locator tool (here).

The flowers were of course attracting insects and one of my main highlights of the day was not only seeing, but also photographing quite well a White-lined Sphinx moth. As well as poking around Hi Vista we also stopped at a couple of other spots that looked like they might hold potential for future exploration, but didn’t come up with anything particularly out of this world species wise.

It was a fun morning of birding and I’m hoping I can sneak out here for a little more before the bloom fades or I have to leave for a mid-April Texas Tour that I will be co-leading for Wildside Nature Tours. There’s still one open space if you are looking for a short but sweet adventure in that incredible part of the world (details here). There are some more photos from the day on my flickr page (here). Thanks to Naresh Satyan and Mickey Long for flower identification.
