DAY 10 OF MY VACATION. I got up around 6:30 this morning, expecting to meet with an on-line friend, Dee, at the Nimbus Fish Hatchery. Dee had to cancel at the last minute because her dog got skunked, but I decided to go to the hatchery for a walk anyway.
There wasn’t much of anything at all to see there. The migrating waterfowl haven’t arrived yet, and the salmon ladder wasn’t operating. But I did get to see some of the salmon in the river; their humped backs appearing through the surface of the water here and there. I also got to see a few birds: California Gulls, Herring Gulls, Common Mergansers, and a female Belted Kingfisher rushing back and forth along the riverbank. There was a Great Egret walking along the netting on the top of the fish raceways, trying to find a way in, and it actually made it in somehow for a little while. As soon as the employees realized it was in the raceway, they opened gates and shooed it out again. I’ve seen Green Herons (who are much smaller and can hide more easily) inside the raceways just gorging on fish. That Great Egret could’ve taken a lot of the larger fish if it hadn’t been seen as early as it was.

The fish in the raceways “know” that when a shadow moves along the side of their enclosure, food is probably coming, so they go crazy – jumping and splashing, opening their mouths for fish-food to fall into. There are buckets along the raceways filled with food you can take to the fish, and every now and then, a truck goes by spewing food out of the side of it like a leaf-blower.
In a sort of gully/barrow pit next to the raceway area there were several Mallards, a Great Blue Heron and a Snowy Egret wading through the rocks and water looking for tidbits. I was able to get quite a few photos of the heron, but actually, some of the insects in the area were more interesting. I found a Mayfly, several ladybeetle nymphs and pupa cases, a large gravid praying mantis, and Green Stinkbugs, some of their eggs and several nymphs in different stages of development.
As I was leaving, I got a glimpse of a beaver swimming on the edge of the bank but lost it when it ducked underwater.
