I got up around 6:30 AM with the dogs to very chilly temperatures (in the low 40’s) and some cloud cover. The weather was very weird throughout the day. There was a short period of rain in the late afternoon… and it snowed in Napa.
Around 7:30 AM, my dog Esteban and I went to the WPA Rock Garden and William Land Park for a walk. Esteban was a very good dog throughout, and didn’t pay the ducks or geese around the ponds any mind, even when they honked and hissed at him.
The WPA Rock Garden was showing off with spring blooms everywhere, and the Smoke Trees were rally “smoking”. The irises around the garden were pretty much spent for the season, but there were various colors of columbine all over the place: yellow, orange, purple and white. I think those are such interesting flowers. They look like alien rocket ships to me. I was also happy to see a lot of native Elegant Clarkia in bloom throughout the garden. That species is new there; I’d never seen it there before. I couldn’t find any milkweed, however, which was kind of disappointing.
There was fennel growing in several parts of the garden, some of the plants in bloom with flowerheads reaching up 10 or 15 feet over my head. But I didn’t see any Anis Swallowtail caterpillars on the plants. In fact, I didn’t see many insects at all and I attributed that to the fact that it was chilly outside and they weren’t awake enough yet to be buzzing around.
In the park, I was hoping to see some warblers (before they migrate out of the area), but actually didn’t see many birds beyond the usual suspects.
I watched a male Mourning Dove collect twigs and bits of grass for a nest for his mate, and saw him carry them inside the convolutions of a huge cactus plant at the edge of the garden. I thought that was an ingenious place to settle on as a nesting spot. The nest is shielded by the large flat fronds of the cactus – and the cactus thorns.
I heard a Mockingbird in a tree making a one-note call and tried to see what that was about. I think it might have been a juvenile, based on its darker eye and lack of repertoire.
Cornell says: “…Eye color darkish [in juveniles]; iris of adults is brighter yellow… Males give a low amplitude, high-pitched nest relief call from a shrub or tree near the nest before flying to the nest site. This occurs during the first half of the nestling period when the female is likely to be brooding…”
I couldn’t find anything specific to juveniles’ calls except that their song repertoire isn’t developed until they’re older. Some of the repertoire of all mockingbirds is learned from other mockingbirds rather than through hearing and mimicking the songs of other species – as well as car alarm sounds, the beeps of microwave ovens, and other human-made noises.
Cornell says: “…Mockingbirds have extraordinarily diverse song repertoires consisting of acoustically distinct song types (= song patterns = syllable patterns). Temporal and frequency characteristics are summarized by Wildenthal. These songs are acquired through imitating the calls, songs, and parts of songs of other avian species, vocalizations of non-avian species, mechanical sounds, and sounds of other mockingbirds. The proportion of songs imitated is not known and would be extremely difficult to estimate because the entire auditory experience of an individual would need to be known to determine whether a vocalization was acquired through imitation. Geographic variation, although not studied, is likely, given that mockingbirds are relatively sedentary, acquire songs from neighbors, and imitate other species characteristic of the local avifauna…Seasonal singing behavior in males appears to be influenced by testosterone levels in the blood… During the breeding season, males typically begin to sing 0.5 to 1 hour before sunrise. Unmated males start earlier than mated males. Song is prevalent during the morning, with its incidence declining gradually until dusk. Cessation of evening song is associated with sunset (light intensity), not temperature. Throughout the day, unmated males sing more often than mated males… The vocal repertoires of individual males have been estimated to be as low as 45 and as high as 203 song types. Wildenthal reported a male in Kansas with an estimated 194 song types and one in Florida with 134… Mockingbird song has received much attention from a sexual selection perspective. While both intrasexual (i.e., male-male) and intersexual (male-female) functions have shaped mockingbird singing behavior, it appears that song serves mainly to attract and stimulate females…”
The middle pond was overrun with lotus again, leaving very little space for the geese and ducks to swim in.
I saw groups of goslings, but the parent birds, including a large Graylag Goose, were being very protective of them, herding them away from my camera, hissing at me, threatening to chase me. I didn’t know if the Graylag Goose had goslings of her own in the creche, or if she had taken on the role of “helper” for the Canada Geese, but she was blatantly aggressive and didn’t want me anywhere near her charges. I don’t tangle with goose-mamas, they will kick your ass.
Among the geese, there was one who had the markings of a Canada Goose but also had an extra band of white around the base of its bill like the Swan Geese often have. Maybe it was a hybrid.

There were more Indian Runner Ducks at the ponds than I’d seen before. I don’t know if more adults were brought in or if the existing ducks had babies last year.
In the water, I saw a group of three tiny ducklings. They were swimming around by themselves, crying loudly for a parent that wasn’t answering them. So sad. I don’t know if their mom was killed or had simply abandoned them, but none of the other ducks in the pond were paying any attention to them. The little ones can survive if they can find enough to eat – and can avoid predators – but I felt really bad for them and their predicament. They were “dark” little things, so I thought maybe they were Wood Duck babies rather than Mallard.
There were a few Black Phoebes flying around the lotus plants in the lake, landing on the bent-over stems that poked out here and there. I saw two sitting next to one another, and one bird gave the other bird an insect to eat. I thought at first they might have been a mated pair, but then it occurred to me that it was probably a parent feeding one of its fledglings. That notion was supported by the fact that there were four or five phoebes flying around the same area. Kids were probably testing their wings, and parents were bribing them with treats to keep their wings moving.
I know where a phoebe’s nest in the park, so I went to look for it, and found a single fledgling sitting on top of it. When it saw me, it flew up onto a nearby ledge. So it was mobile. Maybe it thought if it stuck with the nest, its parents would come there to feed it.
I saw quite a few turtles along the edges of the ponds, and most of them were Red-Eared Sliders. I did see one or two Pacific Pond Turtles, though. They’re the natives; the Sliders are invasive. I saw nine Sliders all basking in the same spot, big turtles and little ones.
As I was heading back to the car, I could see movement on the trunk of a tree across the street, so I aimed my camera at it. It was a female Nuttall’s Woodpecker.
The dog and I ended up walking for about 3 hours and then headed back home. This was hike #26 in my #52HikeChallenge for the year. I’m halfway through and it’s only May. Right on track.
