Puffball

A barn swallow sits atop a cattail at Ridgefield National Wildlife Refuge

In the air, swallows have a sleek, aerodynamic shape designed for close maneuvering so they can catch insects in flight. You’d never know it from looking at this little puffball, with his feathers puffed out he gives a false impression of being rather plump. Many birds will do this when they are cold to create pockets of warm air, much like a hiker dressing in layers.

Treefroggery

Pacific treefrog clinging to a blade of grass at Ridgefield National Wildlife Refuge

This is not only the same treefrog I’ve posted before, but it is literally the next picture I took. Kind of funny that my two favorite pictures of it were taken back to back. It changed positions a bit and then climbed down onto a leaf to lay down.

Why They Go To All This Trouble

A red-winged blackbird fledgling perched in a patch of cattails at Ridgefield National Wildlife Refuge

Red-wings spend a lot of effort raising their young, from when they start staking out their territory, defending their nest, to feeding the hatchlings.

This is the reason for all that effort, a fledgling that flew a few feet from the nest, paused for a few seconds, then flew right back to the safety of the nest.

Like with many species of birds, both male and female hatchlings resemble the adult female in coloration, but one look at the over-sized eyes and beak tells you this youngster hasn’t been out and about for long.

Mouthful

A male red-winged blackbird sits on a cattail with a mouthful of caterpillars at Ridgefield National Wildlife Refuge

When the young are born, male red-wings spend less time vocalizing from the tops of the cattails and more time on the ground gathering food for their little ones.

This male had gathered a mouthful of caterpillars but still couldn’t resist the urge to call out before popping down into the nest. He kept his mouth closed and didn’t extend his body like he usually would have, so I was surprised at how loud the call was.

Giving the Boys the Business

A female red-winged blackbird perched on a cattail at Ridgefield National Wildlife Refuge

While her mate was singing from the tops of the cattails, this female red-winged blackbird was often out of sight down in her nest.

When anything flew into her airspace, however, she popped right up and chased off the intruders. It didn’t matter if they meant her or her eggs any harm, everything from yellowthroats to wrens to sparrows to yellow-headed blackbirds got the heave ho. I spent many hours watching her little patch of the marsh and had to work quickly to get photographs of the other birds before she’d chase them off.

I found the deference shown by the yellow-headed blackbirds the most curious as they were physically larger. They’d fly over to sing, she’d immediately go after them, they’d give her a bewildered look before heading back to the quieter interior of the marsh. After a few weeks of getting hassled, one male yellow-head did return the fight and they squabbled in the air for a while. I thought the larger bird would win over the female red-wing, but her wingman (her mate) joined the fray and the yellow-head retreated to safety.
