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 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.

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.

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.

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.

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.
