Alameda Wildlife Refuge

This morning, I joined about a whopping 80 participants who came to the Alameda Wildlife Refuge for the last workday of the year before the California least terns come back to breed. The Friends of Alameda Wildlife Refuge (http://www.fawr.org) organize work parties on the second Sunday of each month from September through March, then keep watch over the terns during their nesting season from April through August. The endangered California least tern colony is threatened with construction of a VA facility inside what was supposed to be a wildlife refuge.

Each year, about 800 California least terns fly over a thousand miles from the south to Alameda, CA, to breed. The nearest large colony is 150 miles to the south! Habitat loss has driven the terns northward looking for a refuge and now that refuge is threatened despite alternative locations nearby that are outside of the refuge. Look at Golden Gate Audubon's website for information about how you can help fight to protect this endangered species habitat and community open space.

I saw a few birds in between cleaning up the mountains of plastic rubble. There was a redtail hawk on a nearby building with its nest. In the wetlands, the American avocets had changed into their orange breeding plumage. Killdeer flew about chastising the people for being in their territory. I saw a Pacific loon among the Canada geese, scaups, and western grebes.

Afterward, I stopped by Lake Merritt - the center of my "birdiverse" - to see what changes are happening amongst the birds. The tufted duck remained near the bird islands and was spotted among the Greater and Lesser Scaups. The Western and Clarke's Grebes were dancing on the lake at times. In addition to the pied-billed grebe, I saw eared grebes and horned grebes that are beginning to shift into their amazing breeding plumage - a sure sign that spring has come. Five species of grebes calling Lake Merritt home right now. I also saw -
  • Common Goldeneyes
  • Canvasback Ducks
  • Ruddy Ducks
  • Bufflehead Ducks
  • Mallard Ducks
  • American Coots
  • Snowy Egrets
  • Great Egret
  • Black-crowned Night Herons
  • Double-crested Cormorants
  • Ring-billed Gulls
  • Western Gulls
Now if only people would stop feeding the birds! I can't even tell you how many people were feeding the pigeons and ducks. It's too bad Oakland won't post signs. Bread to a hungry bird is like popcorn to a human - just filler without much nutritional value. Plus, it ends up benefiting birds like pigeons and geese, which are overabundant in the area. The leftovers can attract rats and other pests. Please don't feed wildlife! It's a lot of fun, but the consequences are too great for birds, people, and the environment.

Instead, plant a bird-friendly backyard or restore wildlife habitat if you love birds and other wildlife. That's the best thing you can do for them!

Lake Merritt, Oakland, CA

This evening I finally had the first opportunity of the new year to visit my local birding spot and the epicenter of my birding universe - Lake Merritt.

Lake Merritt is one of Oakland's many gems. In 1870, the lake's value as wildlife habitat was so acknowledged that it was designated the first wildlife refuge in the United States. It is an amazing wintering ground for birds and I always stop and look even if I'm without my binoculars or bird book. I especially like watching the channel as the tide goes out.

My main goal for the evening was to spot the Tufted Duck that has been wintering on the lake. Tufted Ducks are diving ducks that are smaller than the Greater Scaups that dominate the lake, but because of similar black and white coloring almost blend in if you're not looking. Luckily, as I was watching the Pied-bill grebes and Clarke's Grebes amongst the scaups near the bird islands, I caught the tuft of the Tufted Duck poking out as its head was tucked under its wing in the cooling evening. Tufted Ducks have been regular visitors in small numbers to Lake Merritt over the years, but it's still fascinating to think this bird made it over from somewhere in Eurasia to our humble lake. I think it would be fascinating to do a satellite track of where it flies back to in the spring.

The other interesting thing I saw was a smaller raptor in the trees of the bird island that normally hosts a lot of Double-crested Cormorants. I couldn't ID the bird because it was getting too dark, but I'll be back to see what it was.

What all did I see in my short evening bird walk?
  1. tufted duck
  2. greater scaup
  3. ruddy duck
  4. canvasback duck
  5. pied-bill grebe
  6. western grebe
  7. Clarke's grebe
  8. mallard duck
  9. coot
  10. Canada geese
  11. bufflehead
  12. great blue heron
  13. black-crowned night heron
I'm sure that I missed some others, but not bad for just an hour.
