Here are some more photos from the Sacramento National Wildlife Refuge. CLICK HERE to see the album.
I got a video snippet of a muskrat. It waddled up onto the auto-tour road, grabbed some green vegetation and went back into the tules. I wonder if it’s setting up a “nest” there. Where they’re able to, muskrats will burrow into the bank and set up a nesting hole in the ground (with an entrance to the water). If they can’t do that, then they’ll create a structure called a “push-up” made of reeds, vegetation and mud… There are heaps of dead tules in places along the edges of the wetland areas at the refuge, including several of them along the auto-tour route, which I think might make building a push-up really easy for the muskrats…
I saw some Great Horned Owls dozing in a tree, but they were so obscured by branches and twiglets that the camera couldn’t figure out what to focus on, so I couldn’t get any decent photos of them. And I saw a Killdeer running and squawking along the edges of a slough. At first I didn’t know what it was excited about, but then I could see it had some babies with it. One of the youngsters was loitering along the water’s edge, and mom was having a fit because it wouldn’t follow her. Hah!
I also came across a pair of Double-Crested Cormorants (on the little island they often share with the pelicans and ducks), and watched while one of them did a jumping and barking kind of dance around the other before it took off and landed in the water behind the island. I’d never seen that behavior before, so I looked it up.
“…Ritualized agonistic displays are associated with takeoff and landing in both sexes. Before takeoff, individual stretches neck in direction it wishes to go, inflates head and neck and gives t-t-t-t-t call through almost-closed bill. Before landing, often calls urgurgurg and gives Kink-Throat Display, which is given also during working of nest material; lowers hyoid apparatus, making orange pouch conspicuous. Immediately after landing, gives characteristic post-landing display in which it holds head horizontally and slightly below arched and inflated neck. These displays also precede and follow a hop, which functions as symbolic or reduced flight, and occurs in various social contexts…” (https://birdsna.org/Species-Account/bna/species/doccor/behavior) Hah! How interesting!
The one thing I saw a lot of out there today was insects: lots of butterflies, dragonflies and spiders. I was happy to see one beautiful Anise Swallowtail, and I also saw some Monarchs, but none of them sat still long enough for me to get photos of them. Among the other insects spotted today were: Variegated Meadowhawks, Garden Orb Weavers, Widow Skimmers, Common Buckeyes, West Coast Ladies, Cabbage Whites and Sulphurs, a Meadow Katydid nymph, Crescent butterflies, Painted Ladies, Pipevine Swallowtails and Yellow-Faced Bumble Bees. I also found a dead Green Darner dragonfly that was pretty well desiccated by the heat. It’s always sad to find them dead, but the find gave me the opportunity to get some close-ups of the dragonfly’s head and eyes…
