Readers’ wildlife photos

Send in your wildlife photos! I am almost out. Thank you in advance.

Today we have miscellaneous photos from the Catskills taken by reader Jan Malik. Jan’s captions and IDs are indented, and you can enlarge them by clicking on them.

Here is another batch of pictures from my hikes in the Central Catskills this April and May. They are not too artistic, given the fast pace that a weekend backpacking hike demands, but they give a sample of what common animals a casual hiker can see in these “mountains” (the Catskills are an eroded plateau and, despite being steep in places, they are too low to have an alpine zone).

White‑tailed deer (Odocoileus virginianus), right in the parking lot at a cloudy sunrise. It was slurping water from a muddy puddle despite a clear stream flowing nearby, so it must have been leftover salt that attracted this ungulate. Woodstock residents like their roads well salted. One has to drive carefully at dusk around Woodstock, as there are many deer browsing on lawns and gardens.

In the woodland, I found the first of many red efts of the Eastern newt (Notophthalmus viridescens). This is an intermediate land stage of development between the aquatic larva and adult forms. Red efts have lungs, but air exchange through the skin is also important, supplying 30–40% of their oxygen demand. They travel through the forest litter when it is humid enough—after rain or in the early morning:

This is probably a blue‑headed vireo (Vireo solitarius), collecting nesting materials. If my identification is correct, then it is not possible to tell a male from a female, as they are sexually monomorphic and share rearing duties almost equally. Interestingly, however, a female may desert the nest just before fledging to mate with another available male:

Possibly an Eastern comma (Polygonia comma), found at higher elevation:

Black‑and‑white warbler (Mniotilta varia). I think this is a male. If so, he may be led by a female into the territory of another male to provoke a fight and allow her to judge his fitness. These birds occupy a similar niche to nuthatches and brown creepers; they climb and circle tree trunks to find arthropods:

Eastern towhee (Pipilo erythrophthalmus), male. These colorful sparrows hang around the edges of forest clearings:

Eastern American toad (Anaxyrus americanus americanus), hiding in a ramps patch. I wonder whether they would prey on red efts or if the efts’ foul taste would be a deterrent:

While passing through oak woods rich with acorns, I heard many alarm chirps from Eastern chipmunks (Tamias striatus). Most made themselves scarce as I approached, but one remained on guard duty:

Not a good picture, but here is a dark‑eyed junco (Junco hyemalis). These are hardy birds, staying year‑round in the forest. In winter they form close‑knit flocks with a few dominant individuals and a strict pecking order:

Chipping sparrow (Spizella passerina) on the side of a quiet road. These migrate to more southern states in winter and in summer nest closer to human settlements:

Mourning cloak (Nymphalis antiopa). There were a couple of them in the area, continuously jousting in the air for control of the territory. I see them every spring in that exact spot, but this year they were too engaged in battling each other to stay still, so this is a picture taken a few years back:

Brown creeper (Certhia americana), shown here just a moment after eating a couple of mayflies. They are common enough, but I rarely see them due to their near‑perfect camouflage. Without directly comparing the bill length it is difficult to tell a female from a male:
