Felis catus
Behai Park, Beijing, 2008-04-18

Before I get on the plane to China I thought I’d try to catch up on recent birding events, since hopefully even with Beijing’s notoriously poor birding and my inability to recruit a local guide, I’ll pick up quite a few species I’ve not seen elsewhere.

Saturday, April 5, I woke up at 5:00 A.M. to get out to Huntington Beach at 6:00. The occasion was the quarterly bird census at the Huntington Beach Wetlands Center. This is about 100 acres of mostly salt panne habitat along Pacific Coast 1, mixed in with industrial plants, housing, and roads. Somehow several large and small parcels have been saved from the sprawling development of Huntington Beach, and the hope is to save more. Restoration projects are scheduled planned to improve the habitat, so we’re counting the birds to track the effects of this eventual work. Plans are to dig a channel to flood some of the areas starting this September. Censuses have been ongoing for about a year and a half now to establish a baseline to measure the success against.

My team of four people (me + Tom Dixon, Pat Cabe, and Dick Cabe) covered the first three parts of Magnolia Marsh. This is a contiguous rectangle divided by habitat into zones 1, 2, and 3. Zone 1 is a narrow riparian strip along Pacific Coast 1. Zone 2 is mostly salt panne in the middle of the plot, and zone 3 turns from the centerline of the levee, southwest to the border of the salt panne. A small canal borders Zone 3 parallel to Pacific Coast 1, but was not included in our territory. Other teams covered zones 4 through 19, including several areas not usually open to the public.

It’s definitely nice being in a new location this year where I can see almost 50 species in under two hours on a casual stroll after work in early April. Where I come from back in Brooklyn, that would take quite a bit longer, 50 isn’t really possible this time of year. I can’t imagine what migration will be like out here.

Thursday I added three species to my walking BGBY list: Clark’s Grebe, Northern Rough-winged Swallow, and Caspian Tern. I find that if I visit each site about once a week, I’m virtually guaranteed to add something new. Daily visits don’t always turn up new birds though. It helps that there are about 4 distinct habitats within easy walking distance of me: urban park, freshwater marsh, canyon scrub, and coastal inlet.

Friday I wasn’t even explicitly birding. I just ran out into Mason Park to grab a few quick insect photos to try a new camera, and I still added one more bird for the year: Ash-throated Flycatcher.

I found several Mourning Cloak (Nymphalis antiopa) caterpillars and chrysalises on a small restroom strcuture in Mason park these last few days. This one is just getting started:

I’m not sure how long it takes one to spin a cocoon. This caterpillar and another were in exactly the same positions 18 hours later.
