Hummingbird Clearwing

These are one of my favorite moths, the Hummingbird Clearwing:

  • They're big enough to see without (much) difficulty.
  • They're colorful enough to take a good picture.
  • They can be found in places I go to find butterflies and other pollinators; I don't need to go someplace I wouldn't be anyway.
  • If I mistake something else for the Hummingbird Clearwing, that something else is also pretty cool (usually an actual Ruby-throated Hummingbird or their Snowberry Clearwing moth cousins).
Unfortunately this is the only picture I've gotten of them this season. I was scouting around Oak Meadow to see what was around a couple days before the annual Duke Farms Butterfly Count when I saw this one hovering around the Wild Bergamot.

It's claimed that these moths are migratory but I haven't found anything on where they spend the winter. Their range goes pretty far into Canada, so it wouldn't surprise me if they overwinter here in NJ. If they do, their strategy is to be ready to pupate before the cold weather hits, burrow into the ground, form a pupa underground, and spend the winter in this state. When things warm up in spring, they can emerge as moths. When raised in captivity, they're placed in a refrigerator to simulate winter; it does appear they expect to deal with some level of cold.

Northern Watersnake

Image
This April I went to Great Swamp National Wildlife Refuge with the hope (among other hopes) of seeing the Northern Watersnakes during mating season. There were 2 problems with this: I think it was slightly late in the season for this. The boardwalk trail where I had seen them in the past was partially closed due to repairs. So although I didn't see any of the 2+ intertwined snakes that I'd seen in the past, but there were still Northern Watersnakes warming themselves in the sun: April 13, 2023 at Great Swamp Photo 272117862, (c) jpviolette, some rights reserved (CC BY-NC) And here's another one coming out of the water.

Female Brown-headed Cowbird

Image
Like quite a few birds, this bird is easier to identify when spotted with her significant other ; she's a Brown-headed Cowbird . Due to their tendency to be monogamous plus plain old birds-of-a-feather behavior, I usually see them with prominently brown-headed males around, greatly improving my confidence in IDing them. My understanding is that Brown-headed Cowbirds are the only obligate brood parasites in my area. Obligate brood parasites have essentially lost all their parenting skills, and thus if they were ever unable to fool other birds into raising their young, they would (almost certainly) go extinct [1]. There are, however, other brood parasites in New Jersey. These are called facultative brood parasites, and these birds will usually raise their own offspring, but will also engage in brood parasitism. (Exactly when birds perform facultative brood parasitism seems variable; one source said it occurred when resources were scarce while another said it occurred when resource

Rooftop Turkey Vultures

Image
I met these Turkey Vultures by just walking out of my apartment. (I theoretically could have gotten a picture without going outside, but that extra layer of glass can degrade picture quality a little.) Although they don't show up on these rooftops daily, they're not an uncommon visitor to my apartment complex. Similar to this spot of the woods , I wouldn't expect this to be a great place to find carcasses. I'm thinking they're here mostly because: They don't have to worry much about predators up there. They get a pretty good view of the area in case something should happen to succumb. (This apartment was near the top of a hill, providing a better view than most of the other apartments.) Since this picture was from February, it's probably a slightly warmer spot, especially near those furnace vent pipes. Although these are Turkey Vultures, it's also not unusual to see Black Vultures up there too. February 28, 2023 at Finderne Photo 264703396, (c) jpviole
