Mystery of the Moth

A giant moth landed in our swimming pool.

It couldn’t swim, but not for lack of trying. The moth pushed and pulled its wings, as though doing the breaststroke. Bert pulled the creature from the water.  The soaked moth flapped its wings, turning quarter circles on the pool deck.

But the hot concrete was scorching my bare feet. I thought the insect might fry before it had a chance to dry out and fly.

Food for Courage

An all-caterpillar diet does not have to be boring.

That’s what I concluded as I watched Baltimore Oriole parents feed their nestlings during my recent nest-watch. They brought wiggly larvae in all colors, sizes, shapes, and textures: green, white, black, skinny, plump, smooth, striped, bumpy, and hairy. Aside from the occasional dragonfly and moth, the nestlings’ diet seemed pretty predictable.

Until they were about four days old.

Watching and Wondering

Watching a bird incubate is not very exciting.

Lady Baltimore spends most of her time in the nest. So, I spend most of mine watching her sit. Or rather, watching her tail, which is mostly all that I see. By my calculations, it’s about time for her babies to start hatching, one per day for four or five days. And a cowbird, too, if the interloper I caught scoping out the nest managed to lay an egg inside.

So, I’m watching that unexciting nest closely, looking for any movement that might suggest hatchlings within.

Hanging by a Thread

The Baltimore Oriole poked and pulled on her growing web of thread.

I was fascinated by her nest-building technique. Her work seemed somewhat random, yet over just a few days, the tangled thread evolved from loose and flat to a tightly woven, multi-layered pouch. Her construction project took about eleven days to complete. I marveled at how a bird’s instinct could guide such intricate weaving.

But Lady Baltimore’s work was not without drama.

In a Terrible Tangle

The male Baltimore Oriole hopped onto the nest-in-process.

I was watching the early days of oriole nest construction. The male stopped by periodically, but not to weave, because the female does all the work. He would hop in, poke his beak at a few strings, and hop out. Cornell’s Birds of the World explains that when the male visits the nest, it’s usually to inspect his mate’s handiwork. And based on what I saw, he often messed it up, yanking out stitches as he fumbled in the tangled web of string.

But one day—the third day of construction—I watched in horror as the male, dubbed Lord Baltimore, didn’t just tug on the stringy nest material.

He got himself stuck.

High Crimes

Curious, I thought.

A female grosbeak went inside a Baltimore Oriole nest. At least, that’s what I thought I saw. But after I posted a video on Facebook and Twitter, several friends corrected my error. The interloper was a Brown-headed Cowbird.

And that’s not good news for the orioles.

Milady Makes a Nest

Baltimore Orioles are building a nest outside my window.

Thinking they deserve better than he, she, or it, I asked Facebook friends for names. I reminded everyone that five years ago, we named some nesting Pileated Woodpeckers Lucy and Ricky, inspired by their blazing red crests. For my new bird neighbors, friends suggested Fred and Wilma, Bogey and Bacall, Cal and Ripken, and Earl and Weaver, among others. But my favorite names were (sorry, baseball fans) Lord and Lady. I’m sure Cecilius Calvert and Anne Arundel, the Second Lord Baltimore and his Lady, wouldn’t mind.

A Labor of Leaves

Squirrels are industrious little creatures.

They’re famous for indefatigable filching at bird feeders. For hoarding and hiding nuts. And for building dreys, those treetop nests made of seemingly random clumps of leaves. But there’s nothing accidental about drey fabrication. The nest has multiple layers for warmth and strength. Dreys are carefully woven shelters that withstand severe winds, hail, and driving rain. Here’s a cross-section view one blogger posted.

I’ve never witnessed a drey construction project. Don’t I wish I could film that bit of creature behavior! But this spring, I watched a squirrel use leaves to great advantage in a tree cavity.

A Red-bellied Predator

The persistent pounding caught my eye.

A woodpecker appeared to be pecking for prey. Red-bellied woodpeckers have a varied diet. Cornell’s Birds of the World says their main fare consists of fruits, nuts, insects, lizards, tree frogs, and the eggs and nestlings of small birds. But a woodpecker could take those foods in a single snatch. It seemed odd that the bird was taking so long to snag his prey.

Looking at my camera’s tiny screen, I couldn’t identify the woodpecker’s quarry. The bird flew off after some two minutes of work,  and I stopped filming. I didn’t give him another thought.  That is, until later when I downloaded the video.

My full-screen view revealed a horrifyingly fascinating sight.

One Plucky Bird

Tufted Titmice are fearless little critters.

I’ve seen them squabble with much larger birds. They don’t hesitate to steal leaves from occupied squirrel dens. Yesterday, I watched one Tufted Titmouse gather nest material.  Her method doubled my respect for these birds’ pluck.

People sometimes toss hair outside, hoping birds will use it in their nests. Some birds forage fur from roadkill. But the Tufted Titmouse has another source for nest material. She harvests hair from sleeping animals. Dogs, squirrels, and raccoons are common targets.

Yesterday, I saw this seemingly reckless bird behavior with my own eyes.
