Nest Box Update 2.21.23

Top Photo: Eastern bluebird eggs (from previous season). It’s early in the season. I usually don’t start next box checks until March. But the warm weather and singing birds had me anxious. And, the fact that there were a few pine needles in one of the nest boxes last week as we placed new berry baskets in them, had me curious too. Two of our nest boxes showed activity, not much, but some interest by the birds. The nest boxRead more

Immature Plumage

Top Photo: Adult male hooded merganser. The next time you’re down in our wetlands, scrutinize the female mergansers. One of them may be a male. Adult male hooded mergansers (photo above) are easy to pick out in a crowd. Their chestnut sides, black back, black and white breast, black and white crested head, and amber eye stand out, for sure. Females are a bit more cryptically plumaged. They’re the ones who will be incubating the eggs inside a tree-cavity nestRead more

The Cooper’s Hawk

Top Photo: Cooper’s hawk in courtship display flight over museum. While spying on hooded mergansers in our wetland here at the Museum of Life + Science, I noticed one of the ducks tilt its head to the side and glance skyward. Reasoning the merganser was eyeing something potentially hazardous to itself, I too craned upward, thinking it perhaps an eagle or other worthy raptor. There, way up high against a severe clear sky was a Cooper’s hawk. It’s stiff postureRead more

Spring Already?

Top Photo: Male hooded merganser swims past a bale of turtles out basking on a warm February afternoon. Basking turtles, excavating nuthatches, blooming honeysuckle, sunning anoles, and mating hawks, all a part of the spring to come. Sliders come out on every available sunny winter day to bask, but they were out in force on a sunny 70 degree day this week. Brown-headed nuthatches commence cavity construction in soft-wood trees each February. They excavate many more holes than they useRead more

Frenzy*

To Photo: Oak and Niko. There are four stages to the canine estrus cycle (reproductive cycle)—proestrus, estrus, diestrus, and anestrus. Proestrus is the stage where the female’s estrogen level peaks. Proestrus lasts for, on average, 9 days. Males are attracted to her but she is not receptive to them. Estrus, which also averages 9 days, is the fertile period. Estrogen levels drop and proestrogen levels rise. More importantly, the female is receptive to males. Diestrus lasts for about 2-3 months or until theRead more

Holly Berry Time!

Top Photo: Cedar waxwing surveys the area for berries. Keep your eyes open for cedar waxwings and American robins raiding the holly trees and bushes around campus. Each year the two species flock in and often pick clean the American and yaupon hollies of their fruit. Even the eastern red cedars take a hit. The fun usually starts in February. It’s February now! American robins can be seen locally in every month of the year. Waxwings are nomadic and mayRead more

How Close Can You Get?

Top Photo: Ranger Patrick (lower right) photographing one of the local red-shouldered hawks (beyond and to right of pine tree – large tree trunk on left). Our resident red-shouldered hawks are quite used to human activity. When they’re hunting they seem to pay little or no attention to folks passing by. In the heat of the breeding season the birds seem even less concerned. They often allow close approach by photographers like Ranger Patrick in the photos here, as heRead more

Ducks, Cherry Dogwood, Crocus, Geese, Sliders, and Mistletoe

Top Photo: Hooded mergansers float and reflect in the wetland’s water. Here’s a handful of things to look for as you stroll around and through our outdoor areas during the last half of winter. We hope to entice hooded mergansers to nest in our wetlands. Cornelian cherry dogwood’s flower buds are about to burst open into a bright yellow display of florescence. The small tree shown here is located on your right, just outside the main building’s door to GatewayRead more

Polyphemus

Top Photo: Polyphemus (pol-uh-FEE-muhs) moth cocoon hanging from twig in Earth Moves. Some silk moths spend the winter in cocoons in the leaf liter. Some burrow underground. At least some Polyphemus moths winter as pupa wrapped up and hanging from a twig or branch of their host tree via a peduncle. The further south Polyphemus moths live, the more likely this behavior. Occasionally, though, these hanging cocoons drop off into the leaf liter. The one pictured here was found hangingRead more
