Around 7:30 I headed over to the Nimbus Fish Hatchery. This was going to be the last day they were going to do the Steelhead spawning, and I wanted to film some of that process for the naturalist students. When I got to the hatchery, nothing was open yet, so I walked the ground for a little while. It was 37º there, but the wind coming off the American River made it feel like 32º. Brrrr!
The visitor’s center opened up at 8:00, which is when the Steelhead spawning was advertised to start… But I was told that it was going to be delayed for an hour or so, so the process could be simulcast to grade schools in the area.
I didn’t want to just stand around for an hour and half, so I decided to brave the cold again and walk part of the trail instead. If nothing else, I could take some photos of that to share with my naturalist class.
Right around the visitor’s center there were lots of Brewer’s Blackbirds, and I also saw some Lesser Goldfinch, a House Finch, lots of House Sparrows and Golden-Crowned Sparrows, and several hummingbirds (Anna’s, I think).
On the river I saw lots of Common Goldeneye Ducks, Common Mergansers (more females than males), Canada Geese, a single Grayleg Goose, Herring Gulls, Ring-Billed Gulls, and California Gulls.
The best find by the river was being able to see gulls and Double-Crested Cormorants lining up on a wire that goes from one side of the river to another. I’m not sure what it’s used for, but the winch-end of the wire is on the hatchery’s side. The cormorants get their “nuptial crests” – that stand out like bushy eyebrows over their eyes — during the breeding season, and we’re right at the beginning of that now. Most of the crests you see are black (which generally means that the cormorant is a resident of California), but occasionally you’ll see one with white crests which generally means they’re migrating down into our area from more northerly regions, like Alaska. I saw one with white crests today. That was a first for me.
The salmon raceways were empty, even the water had been drained out; but on the trout side of the facility, there were Rainbow Trout in various stages of development in every raceway.
Caught inside the structure, too, were a couple of Black-Crowned Night Herons. They must’ve gotten in when someone opened and the forgot to shut the entrance gate – and then got trapped in there when the place was locked up again. They were looking pretty panicked. The only way to get them out would be to open the gates again and shoo them toward the open door. But opening the gates means other fish-eating birds can get into the raceways, too… A conundrum.
By the time I got back to the visitors center, they were halfway through the filming of the Steelhead spawning, and I didn’t want to interrupt that, so I left.
On my way home, I passed right by the American River Bend Park, so I stopped there for a few minutes just to see if I could spot the Great Horned Owl on her nest that I saw the last time I was there. Yep. She was there, sitting on her nest, dozing away. Because the nest is so high and the lighting around it is so bad, I can’t get very good photos of it, but I took a few anyway.
In the same area, I also saw a mule deer in the distance, several Mourning Doves, a few Northern Flickers, Spotted Towhees, Oak Titmice, and an Audubon’s Warbler. It looks like stands of Stinging Nettles are starting to come again – which may be a bad thing for hikers and campers, but is a good thing for Red Admiral butterflies who lay their eggs on the plants, and whose caterpillars depend on them for food and protection. I only stayed at the park for about 30 minutes and didn’t walk any of the trails.
