Top Photo: Immature plumaged yellow-crowned night-heron pays visit to wetlands. Night-herons have been observed in our wetlands four, perhaps, five times. All but one of those birds was a yellow-crowned night-heron (YCNH), the other, a black-crowned night-heron (BCNH). Of the YCNHs, one of them arrived in May and spent most of the 2011 summer. The other birds were only seen briefly, for one or a few days each. As you might suspect, night-herons often hunt at night and sleep awayRead more

Summer Odes
Top Photo: Male blue dasher perched and ready to sally forth. In the photo below a pair of blue dashers mate, assuming the “wheel” or “heart” position. This is when sperm is transferred from the male’s accessory genitalia to the tip of the female’s abdomen where her eggs will be fertilized. As I’ve mentioned before on this blog, great blue skimmers are the largest eastern skimmer. They’re a common sight at ponds, lakes, and slow moving rivers and streams. SlatyRead more
Final Nest Box Update 8.1.23
Top Photo: Eastern bluebird eggs. The bluebird nesting season here at the museum is officially over. There’s no activity in any of our six nest boxes. The table below is a total of all the birds fledged since 2012, when I first began monitoring the nest boxes. There were a total of 36 birds fledged this season. The best years for bluebirds were during the 2012, 2013, and 2014 seasons. Chickadees had their best years in 2013, 2018, and 2023,Read more
Nest Box Update 7.25.23
Top Photo: Eastern bluebird eggs. We are now down to zero nest activity. ————————— The Cow Pasture nest which held five house wren nestlings last week has fledged them all. I could hear them in the woods behind the nest box as we checked in on them this morning. The remaining five nest boxes are empty. ——————————— I’m calling the season over. I’ll make one last trip around the nest box trail at the start of next week, but IRead more
Spiny-backed Spider and More
Top Photo: Spiny-backed orb weaver (Gasteracantha cancriformis) Only about 1/2” wide, spiny-backed orb weavers are distinctive for their shape and pattern. The individual pictured is mostly white with black markings and red spikes. But, they may also be yellow or red with shades in between. The spines may be black. Some suggest the spines may deter predators such as birds or even subterranean-nesting, spider-seeking, solitary wasps. I doubt birds would be put off by the spikes. I must admit, though,Read more
Shedding, Basking, and Waiting
Top Photo: A green anole in mid-molt. Air bubbles are visible under old, shedding skin of the green anole pictured here. Green anoles may shed as often as once a month, or as infrequently as once annually. They may eat their old shed skin. At first glance, the dragonfly below looks to have three pairs of wings, even four pair. In fact, eastern amberwings have two pairs of wings. The illusion is cause by the translucence of the dragonfly’s wings,Read more
Turtle Nest
Top Photo: Eastern painted turtle heads back to water after laying eggs. Painted turtles come ashore each spring and summer to lay eggs. They deposit 2 – 6 eggs in a hole dug by themselves. The eggs take from 70 – 80 days to hatch with some young remaining in nest until the following spring. The turtle’s eggs, like the other aquatic turtles in our wetlands, are frequent victims of predation by terrestrial mammals, raccoons, foxes, and even squirrels. WhenRead more
Nest Box Update 7.4.23
Top Photo: Eastern bluebird eggs. We have one active nest, house wrens for a second brood at the Cow Pasture. ————————— The Cow Pasture nest, as it did last week, has six house wren eggs. I was expecting nestlings. I didn’t see or hear an adult in the area which makes me wonder whether this nest has been abandoned. Though, six eggs is a large investment for these birds to quit. We’ll see what happens next week. The Explore theRead more
Big Eyes, Long Legs, and Bright Colors
Top Photo: Larva of eastern tiger swallowtail butterfly. Many insects have physical features which tend to disguise themselves or to make themselves look larger or more intimidating. Eastern tiger swallowtail caterpillars have “false” eyes on the top of their thorax to perhaps convince would be predators they’re snakes, or at least, that they can see them coming. The individual in the photos is ready to crawl off to find a secure location to pupate. Would you think twice about pickingRead more
