Ducks

Yesterday I went for a walk along Charleston Slough in Palo Alto at high tide. It was a gray day, and the light seemed to make the colors of the ducks appear more dramatic than usual. Looking at the ducks helped me forget the crazy stuff that’s in the news these days.

Green-winged Teal (Anas crecca carolinensis)
American Wigeon (Anas americana)
Ruddy Duck (Oxyura jamaicensis)

Notes: Common and Latin names from Dunn and Alderfer, Field Guide to the Birds of North America, 7th ed. (2017); however, the AOU now assigns American Wigeon to its own genus, Mareca. Photos: inexpensive superzoom camera (cheaper than your smart phone) and free image manipulation software.

Winnemuca, Nev., to Evanston, Wyo.

This morning, I had a hard time getting on the road; a week’s worth of twelve-hour days running Ecojustice Camp finally caught up with me. I was a little bleary when I started driving. Yesterday in a truck stop I had found an audiobook, on CDs no less, of Isaac Asimov’s I, Robot, and I put the first disc into the car’s CD player. When I was in high school, I had loved I, Robot; I found I still liked it, even though there were huge holes in the plot, even though Asimov doesn’t appear to like women very much, even though he mixes slide rules and space ships; I liked it even though the characters were caricatures, but they were engaging caricatures.

At some point after I passed through Battle Mountain, I began to notice how green the mountains looked — green by northeastern Nevada standards, that is. It had obviously rained in the recent past. Then I began to notice the banks of yellow flowers along the edges of the interstate; I could not only see them, but in a few places I could feel the pollen in the air. They ere so stunning in that desert landscape that I finally pulled over at the exit ramp to Welcome, Nevada, and photographed them. They looked bright and dramatic against the freshly green sage brush.

I rolled through dreary little West Wendover, Nevada, its faintly shabby casinos looking even more shabby in that huge landscape, with towering mountains, and the white expanse of the salt flats stretching eastward into the haze. I rolled across the salt flats — stopping briefly to eat a sandwich in the shade of the rest area in the middle of the salt flats — across the plains and hills on the other side, and got off at the Dugway exit. The directions said to head north, take an immediate left, go a third of a mile, then take the right fork. But the road didn’t fork, it terminated in the exit gate of a huge Cargill salt facility, with a railroad siding and towering piles of salt. Finally I figured out that what I was supposed to do was to turn right at the gates to the Cargill plant, and sure enough there I was at the entrance to Timpe Spring Wildlife Management Area.

One moment I was between the railroad siding and the salt plant, and the next moment I was driving along a narrow dirt road looking out at American Avocets and Black-necked Stilts squawking at me, and California Gulls soaring purposefully overhead towards Antelope Island, which loomed out of the invisible Great Salt Lake in the distance, and a Northern Shoveler dabbling at the edge of the marsh with that absurdly long bill it has.

I started walking out across one of the dikes, but Forster’s Terns and Black-necked Stilts began circling closer and closer to me, and Song Sparrows came up out of the brush at the edge of the dike, all of them giving calls of alarm. Obviously, I was getting too close to their nests. So I walked out along the other dike, but soon an American Avocet and a Wilson’s Phalarope came out of the marsh grasses giving their calls of alarm, so I retreated once more. By that time, I had been walking around for most of an hour, and the temperature was one hundred degrees even, and I was longing for a drink of water. I walked back to the car.

The birds were not so bothered by me while I was in the car. I drove out very slowly, stopping several times to see if I could see the nests of the American Avocets and the Black-necked Stilts, but I could not; the nests must have been well down in the marsh grass. I swatted one last biting fly, slow and stupid from the heat, that had landed on my face, rolled up the window, and drove on to Evanston, Wyoming.

Duckling update

The Mallard who is nesting in the basement stairwell of our building had six ducklings two days ago. Carol has been supplying the mother and her ducklings with water and food (greens and rolled oats), but sometime yesterday two of them died of unknown causes. Just now I heard the mother quacking furiously, and I ran out onto our balcony in time to see a white-and-gray cat scramble up over the fence with two ducklings in its mouth. The mother duck followed the cat out to the street and kept quacking in the direction the cat disappeared.

Carol and I met one of our downstairs neighbors in the yard. We all looked down into the stairwell: the mother duck was there with just two living ducklings, and there was blood on the concrete path at the top of the stairs. While I’m sure the mother duck feels safe down in that cosy little stairwell, staying there means that her babies are (as Carol pointed out) sitting ducks for any cat hunting in the neighborhood.

Post script to cat owners: This was no feral cat that caught the ducklings; it was plump, well-fed, and clean, and obviously someone’s pet. I wish cat owners would keep their pets indoors:– it’s better for the cat, since indoor cats are far less likely to get feline AIDS, or to become coyote snacks;– and it’s much better for the birds of the neighborhood, who won’t become cat chow.

Further update: Carol finally called the Peninsula Humane Society & SPCA, who sent an animal control officer. It was pretty clear that in a neighborhood full of cats, the remaining two ducklings wouldn’t last another day. Olivia-the-Humane-Officer arrived at about seven in the evening; the mother duck flew away (apparently a common occurrence), so Officer Olivia had to take the two ducklings with her. In thanks, we made a donation to the Humane Society in honor of “all humane officers.”

Nesting

Carol discovered that there is a female Mallard duck with ducklings living in one of the stairwells that lead down to the basement under our building. When she took the photo below, she didn’t want to get any closer for fear of disturbing the mother duck. The babies are hiding under their mother’s breast.

Carol left some greens and a dish of water for the ducks.

I’m not sure where the actual nest was. It doesn’t look like it was down in the bottom of the stairwell; perhaps one of the babies fell down the stairs, and the mother is down there protecting them.

Summer

At lunch time, I drove down to the marshes at Baylands Nature Preserve. A baby American Avocet stood at the edge of the water swishing its tiny beak back and forth to gather insects and other invertebrates from the water, just like the adult avocets a few yards away. Out in deeper water, a Mallard hen watched carefully over two baby Mallards swimming on either side of her. I couldn’t help noticing the difference in the way the two species raise their young: the American Avocet is a precocial species whose young are on their own from hatching, while the Mallard is an altricial species whose adults care for their babies for some time. It seemed that everywhere I looked I saw birds nesting or getting ready to nest: Cliff Swallows building their nests of clay on the side of a building, Forster’s Terns apparently nesting on a tiny island in the middle of the marsh, Marsh Wrens warbling madly in the rushes.

I looked across the bay at the green hills of the East Bay. Except some of the lower hills at the far end of the Dumbarton Bridge don’t look all that green any more. It’s been warm for the past few days, and it looks like the rains are finally over and gone, and now some of the low hills are turning summer-brown. The higher hills and mountains are still brilliant green, but it won’t be long before they turn brown, too.

Baby birds and hills turning brown: these two markers in time are as good as any to mark the end of the winter-wet season, and the beginning of the summer-dry season.
