Hamerkops

The hamerkop is an African bird whose name means "hammerhead." These photos of the Columbus Zoo's pair are from 2018.


A brown hamerkop stands on black legs. Its black beach is to the right, and its crest of feathers extends from the back of its head.
A hamerkop stands on its nest. The bird is about 18 inches tall.
The hamerkop's wings are several shades of brown.
A hamerkop stands with wings spread on part of the viewing deck in the Congo aviary.
A hamerkop flies left-to-right against a background of greens and browns.
I'd love this photo if the bird were clearer. I cropped it close to emphasize the blurry background that came from tracking the flying hamerkop with the camera.
Two hamerkops are on their nest of straw, grass, cardboard, egg cartons, and other materials. The nest is six feet wide and wraps around a large post.
Hamerkops build large nests, especially considering the size of the birds.
A hamerkop stands with its beak poking into the nest.
A hamerkop carefully adds to its nest.
The hamerkops' nest was removed over the winter. The birds have apparently added the first two handfuls of nest material.
This is "the hamerkops' post" May 20, 2019. I have not yet seen the birds building this year.

Reflections

There are good reflections


Lavender and yellow flowers are reflected in water.

and bad reflections.


The photographer's arms and hands are superimposed on the manatee, thanks to reflection from the manatee tank's glass.
Florida manatee (Columbus Zoo, Apr. 2019). I've learned to wear a dark shirt when I expect to be taking pictures through glass. Maybe I should wear long sleeves and gloves, too.
There are reflections of lights.


An elephant's mouth is open, but reflections of ceiling lights mar the picture.

I bought a circular polarizing filter, which purports to eliminate reflections, for my lenses, but it has limits. For one thing, it significantly reduces the amount of light that enters. When ambient light is low, such as when I'm in the elephant barn, I can hardly see anything through the viewfinder.


There are horrible reflections.

A viewing area that's darker then the exhibit limits reflections, but sometimes there are lighted signs behind the photographer.

A photo for artistic effect? No, I took the picture for the heck of it. It looks like a double exposure, but it's not. The sloth bear is inside the glass and the rock superimposed on the bear is a reflection of what's outside the glass.

The bear's head and torso show  cracks in rock.

I don't take the picture when I'm aware of a bad reflection, and I like to think I've become more aware over time. Still, I'm not always aware, as the manatee photo shows.

Here are a couple more good reflections.

Poor Clyde

Last week, I saw the Columbus Zoo's African grey parrots outside for the first time this year. The viewing deck is about five feet above the ground, and I looked down after I heard a rustle followed by a thump-splat. A parrot had made a hard landing and began to climb the mesh.

 Later I learned the parrot's name is Clyde.

Clyde approaches my eye level.
Clyde's tail was in bad shape, and I assumed this year's feathers hadn't come in yet.


Clyde's tail feathers are ragged and torn.

Then I observed a crime.


A parrot at the top of the picture holds two red feathers in its beak. Clyde is at the bottom.
A comrade has plucked two of Clyde's tail feathers.
(I assume plucking another's feather is a bird crime. Given the importance of feathers, plucking one from another must be a grave insult at the very least.)

Clyde suffered more harassment.


The tormentor nips at Clyde's head.


The tormentor pulls on Clyde's wing.


Keepers arrived and discussed the situation: "I think it's Clyde." "He doesn't fly very well." "Is he bleeding?" They put Clyde into a carrier and took him inside for examination by a veterinarian.

Large flying fox at the Columbus Zoo

Well, this looks ominous.

A flying fox hangs by its feet with wings wrapped around.

Three flying foxes are reflected in a mirror.
At least we know they aren't vampires. Also, these bats eat fruit. (Why is there a mirror? I don't know; it's not there all the time.)
A flying fox hangs with its translucent wings spread.
Here we can see the bat's body. It hangs by its back feet, and each hand has one finger with a hook at the end.

What's not to love?
