Reader Tracy Hurley sent a nice batch of photos; her captions are indented below.
I’m a long-time reader, and I want to help fill your tank with some nature photos.
I signed up for a nature tour at the Seal Beach National Wildlife Refuge, which is a salt marsh habitat on the grounds of the Naval Weapons Station in Seal Beach, CA. This is a monthly tour, and a reservation requires a background check. We were told we could not photograph anything naval-base related, only nature. Fine by me!
A gigantic salt marsh ecosystem used to exist on the coast of southern California, but it has been paved over and fragmented so that only a tiny bit remains. 965 acres of salt marsh is in the Seal Beach National Wildlife refuge. We visited during a low tide, so these photos show the grasses and pickleweed and mudflats in plain view. They are submerged twice a day by high tides.
We saw a lot of Belding’s Savannah Sparrows (Passerculus sandwichensis). These birds have a narrow range and require the pickleweed-dense salt marsh for nesting (and other pursuits). The bird in this photo is in a patch of pickleweed.
Here’s a Marbled Godwit (Limosa fedoa) poking around the mudflats.
Most of these are Long-Billed Curlews (Numenius americanus). There’s a Snowy Egret (Egretta thula) in there, too.
I believe these are Double-Crested Cormorants (Phalacrocorax auritus), plus a few Snowy Egrets and a Western Gull (Larus occentalis).

This light-footed Ridgway’s Rail (Railus obsoletus) was the most cooperative of subjects! The Refuge is providing habitat and rehabilitation to this endangered species. The problem for the Rails at the refuge is that during high tides, their nests float upward with the rising water. Under normal circumstances this is fine, because the nests would still remain trapped in the long strands of cordgrass–the cordgrass holds the nests in place so they don’t float out to sea when the tide goes back out. However, this particular salt marsh no longer gets fed enough fresh water to allow cordgrass to grow tall enough. Thus, the nests tend to float away. In the contraption in this photo you can see one of the hundred-plus nesting platforms installed at the refuge. These platforms float on the rising water, but the vertical bars keep them from drifting away when the tide goes out. The tent over the top protects the birds from predators.
