Little Bear and Some Late Spring Encounters

Top Photo: Little Bear by the waterfall. Little Bear’s pelage stands out among our three black bears occupying the Black Bear Enclosure. The following are subjects you might encounter on our Outdoor Loop Trail in late spring to early summer, now. Two very common and widespread dragonflies, common whitetail and eastern amberwing are sure to be seen on any sunny day. Not as frequently seen but still common are Carolina saddlebags. They spend much of their time on the wing.Read more

Nest Box Update 6.4.24

Top Photo: Eastern bluebird eggs. We have eight bluebird nestlings in two separate nests. Four of our nest boxes are empty with no activity. — The Cow Pasture, Explore the Wild, Into the Mist, and Parking Deck East nest boxes are all empty, but ready to go should any local avian cavity nesters feel the urge. Last week I predicted that the five bluebird nestlings in the nest box on the west side of the parking deck will have fledgedRead more

Nest Box Update 5.21.24

Top Photo: Eastern bluebird eggs. First, thanks to Ranger Kade and Volunteer Sammie for conducting the nest box inspections this week in my absence (everybody deserves a little time off). They did an excellent job checking, photographing and reporting on the nest box activity during the past week. Here’s what they saw. Three nest boxes are empty. One nest box has two eggs in it, but should be labeled empty (will be, hereafter). One nest box has bluebird eggs whileRead more

Cicadas and Other Things Around the Campus

Top Photo: Magicada tredecim, one of two species of periodical cicadas emerging this spring in the Central Piedmont of North Carolina. You’ve most likely heard about the emergence of two broods of cicadas this spring, Brood XIII and Brood XIX of seventeen year and thirteen year periodical cicadas, respectively. Here in Durham and surrounding counties there is no overlap of the two broods but there are two species emerging at the same time from Brood XIX. Magicada tredecim and MagicadaRead more

More Spring Sightings and a Red Wolf Observation

Top Photo: Male common whitetail. Common whitetails are everywhere. Ponds, lakes, even slow moving rivers and streams are home to this ubiquitous skimmer. The standout white/blue abdomen and dark marks on the wings lend to the easy recognizability of the male. The female too, is easily recognized by the three dark markings on each of her four wings. They both tend to perch low to, or directly on, the ground. Another early season dragonfly making an appearance is the blueRead more

Soldierflies

Top Photo: Soldier fly larvae feeding in our wetland. I’m not sure of the species level identification but the larvae in the photos above and below seem to belong to the genus Stratiomys. They’re a genus of soldier fly which apparently lays eggs in the water. The adults are bee or wasp mimics and feed on nectar and pollen. The larvae that hatch from the eggs deposited by the adults eat detritus on the bottom of a shallow, muddy pondRead more

Early Fall Things To Discover

Top Photo: Yellowjacket picking over annual cicada. The yellowjacket in the images above and below is scavenging protein from a dead cicada on the path. Yellowjacket larvae back in the hive are fed protein in the form of whole insects or chunks of meat harvested from caterpillars and other larger animals, even from a picnicker’s ham sandwich. The yellowjackets take the meat back to the hive and feed it directly to larvae in cells within the hive after it’s beenRead more

Katydids

Top Photo: Angle-wing katydid (Microcentrum retinerve). Katydids belong to a group of insects known as Orthoptera which references the straight or parallel-sided aspect of their wings (ortho = straight, ptera = wing). This group includes grasshoppers, locusts, crickets, and katydids. You can usually distinguish katydids from the others by their longer antennae, though some types of crickets do indeed have long, thin sensory appendages. There are many kinds of katydids. The two mentioned here are an angle-wing katydid and aRead more
