Joy Fall

It's fall! Some birds are just totally in shock.
Heron: "DUDE it's NOVEMBER WTF!"

Migrant birds are returning to the lake. Here's a glaucous winged gull that attracted my attention with its strange yodeling call. It sounds quite different from a Western gull when claiming food. Or maybe only when it's claiming a bit of roast chicken someone dumped. I don't know whose action is more surprising: the guy who thought it would be fine to throw a chicken to the birds, or the pigeons who thought it would be fine to eat it. Blech, guys, srsly.

Ruddy ducks have arrived. These are easy to ID at long distances because of the white cheek, and the (usually) long pointy tail.

Ring billed gulls are back too and looking for action. "Hey, where's MY roast chicken?"

And of course scaups. I have vowed that this will be the year I learn to tell greater from lesser. I have long wondered why the majority of scaups I see at the lake are male. One theory I had was that females and males arrived and left at different times. The first one I saw this year was female:

Uccelli Roma

Last month I went to Italy--Rome for a few days, then a week and a half in Sicily. I knew the birdwatching wouldn't be stellar, but I had hopes of seeing at least some common birds that were unfamiliar to me. Heck, even the house sparrow has an Italian version that's all redheaded and crazylooking.

In Rome, I found plentiful evidence that birds had been seen in the past, at least by sculptors:




Hmm, on second thought I kind of doubt anyone saw this whale-bird.

Aaaand unless there were some sculptors observing during the Permian (age of 8 foot scorpions), they probably never saw a peacock THIS big:

On Palatine Hill I managed to find some live-action birds doing a love scene:


Unexpectedly, there was also a small flock of parrots hanging out there. They reminded me of the parrots I see in the Presidio. I don't know my parrots, but I think this is probably a Monk Parakeet. What's the difference between a parrot and a parakeet? DNA. How could a parrot-keet live in a non-tropical location? Well, Rome's not exactly cold, and there's plenty of tourist trash to eat. Also the berries from this tree, which looks like it's a yew.

Hooded crows were also ubiquitous throughout Rome. In fact this was the first kind of bird I saw after landing--perched along the roadside enroute from the airport.


Once we reached Sicily, there was still more artistic evidence that sometime in the past, it was inhabited by grotesque, bug-eyed eagles:

And some human-swan horse-swan hybrids:

In search of actual, living birds, we journeyed to one of Sicily's giant regional parks: Madonie. On the way we stopped at a tiny town called Castelbuono, which was inhabited quite picturesquely by a flock of what I think were crag martins:


They taunted me, perching on nooks in the sheer wall and poking their little heads out.

Also enjoying the nooks of Castelbuono was a big flock of jackdaws. They look like stubby-faced crows. Later on, we saw them perched along the highway, hundreds of them, but all spaced out in pairs.
Another common bird was the collared dove, seen here mooning the photographer with its distinctive white tailfeathers.

Finally, we made our way to an actual wildlife reserve, Vendicari, where we hoped to see the thousands of flamingoes that winter there. Alas, they hadn't arrived yet, but we spotted a few other friends, including this guy, which I think is a redshank:


We didn't find my dream bird (the hoopoe). We asked our host at a bed and breakfast we stayed at about it, but he didn't know the word "upupo." Then I tried to describe it as similar to a parrot, with a crest. He thought we meant the "ghiandaia," (literally "acornist") (turns out that is a jay), and explained that during this time of year they are all up in the mountains eating olives. Something to look for next time, I guess!

The pelicans at home

The newly-renovated boathouse/restaurant opened about a month ago, and I wondered what real estate the cormorants would stink up now that their old pier had been removed. Turns out they seem to have followed their old pier to the other side of the lake, where it's now sinking into the mud.


Here, various birds have had no trouble putting their feet up on the coffee table, and their poop all over the couch. Here we see a white pelican, likely on its way to the coast from breeding grounds inland; and double crested cormorants, which are common in summer but will probably leave the lake soon.

Though they nest in very different habitats, at this time of year the three species cross paths for an interspecific jamboree. And when brown pelicans come sit on the porch, they bring the moonshine. No. Not really. They just hum fragments of "Slough foot Sue..."

The brown pelicans have finished nesting in the islands of southern California and Mexico, and are now heading north...

...with an occasional layover on a crowded dock.

Unlike the white pelicans, brown pelicans hunt by diving from the air with a very impressive splash (which I didn't manage to capture.) Here's one post-snack:

It soon takes off again--

--and loops back around for another attempt. Come on, fishy!

Hangin' with Mr. Cooper's Hawk

I spotted an exciting silhouette atop the bird dome this morning:

Periodically, I see a hawk buzz the pigeons inside, making them flap frantically from one side of the cage to the other. This is the first time I had my camera ready.

I'm not really sure what the hawk is thinking as it circles the cage. Does it think that it could really catch a pigeon if it could just get at the creamy center of the bird-cage truffle? Here it is perching on top of the keepers' entrance. "Ahhhh, for the keyring.... and thumbs. Thumbs would be good."

"Or maybe somebody made a mistake and left a panel open?

"Better check all the welds just to be sure."

Maybe it's just attracted to looking at the pigeons? Here it is taking a human's eye view of them.

They don't like that very much.

But the pigeons really HAAAAATE it when the hawk goes all like:

"Pant, pant. Hunting caged pigeons is harder than I thought. They have some mighty defenses."

I used the "burst" mode on my camera for the first time. I only got one good shot that way, but it was a quite artsy one:

So the key in telling a Cooper's hawk from a sharp-shinned hawk is that the former has a rounded tail and the latter a square tail. Also, Cooper's is slightly bigger. Here is another example of a bird where I just don't have enough experience to compare the two well. This tail looks pretty round... right? But then it also looks slightly notched, which is a character of the sharp-shinned.
This bird was larger than a robin, about crow-sized, which would seem to place it in the Cooper's category. But then the female is larger than the male in most raptors, so if it's a lady sharp shinned, it could be as big as a male Coopers'. Making things still more difficult, this is an immature (=brown 'n streaky) bird. I'm sure the birders monitoring the raptor migration over in Marin could tell easily, but I'm an undecided amateur even with this pretty clear photo.

Anyway, hawks are cool. Happy migration, friend!

Mergansers!

Periodically I will see something unexpected at the lake, like these two mergansers. I've never seen a merganser in brackish water/marsh before, but here they are. They've been hanging around the mallards for a few days now.

Mergansers are fish-eating ducks; they have "sawbilled" beaks to help them grab the fish. The rearmost merganser in this shot has something red on its back, like a leaf is stuck to it or something.

There are two very similar species: the common and the red-breasted (aka more rare). I thiiiink this one is the common, because it has a fairly clear delineation between the red head and grey body, but having never seen the other kind, I'm not really sure.

Good OLD Lake Merritt

The Oakland Museum of California has a pretty cool "virtual collection" of old postcards, photos, posters, and other ephemera. You can search it by Oakland neighborhood, so naturally I used it to see what Lake Merritt looked like back in the day.

1977


1985

One thing I noticed was that there are several duck species in these photos that I have never seen at the lake. In the picture below, you can see a few wigeon(s?) just underneath the swan.

And in this photo you can see an entire horde of pintails thronging to be fed.

1920

I'm wondering if old photos like these have ever been used to collect data on population size.


1922


1920-1950


1930
