Look Up: Paper Wasps by Todd Henson

Paper wasps are very busy creatures.

After hiking for a couple hours through a park it’s often nice to stop and take break, resting in one of the open wooden shelters found in many parks. When you do, if you look up, you just might see one or more paper wasp nests. Perhaps you’ll even see a nest currently occupied with busy wasps going about raising their next generation.

If you look closely at some of the photos (click on them for a larger view) you may see young larvae in the open cells. The queen lays eggs in open cells, which mature into larvae. These larvae will eventually spin a cocoon in the cell, also visible in some of the photos. They will enter the pupal stage in the cocoon, after which they’ll emerge as adult wasps. It’s a fascinating life cycle.

Notice the larvae in the open cells. Those in the closed cells have entered the pupal stage.

Be careful if you do find active nests. Though I’ve never had any problems with wasps, they can be very protective of their nests, attacking if they feel threatened. Best to leave them be, and maybe not stand quite as tall as you normally would if the shelter has a low ceiling. Sometimes I’ll just sit in a corner and watch (and photograph) the wasps as they go about their day. Very interesting and social creatures.

Next time you rest in an open shelter, look up. What do you see?

Osprey Building a Nest on a Windy Day by Todd Henson

Osprey facing the camera on a windy day, with head feathers sticking straight up.

Osprey don’t have it easy. They build nests close to water with no protection from the elements. I’ve seen osprey nests blown over during strong storms. But these amazing birds just keep rebuilding and moving on.

Today’s photos are of an osprey in Colonial Beach, Virginia, building a nest atop some poles just offshore. It’s a very windy day, as you can see in the photo with the osprey facing the camera. The feathers on the back of its head stand straight up with the wind blowing towards me. This really gives the osprey a wild, aggressive look.

Thinking Through the Shots

I wanted to focus as much as possible on the osprey, meaning I wanted the background to disappear in a blur. The distant shore was quite a distance away, which helped. I was shooting at 400mm focal length, which also helped. My maximum aperture was f/5.6 with the setup I was using but I chose to use f/8 to give a little extra depth of field to capture the osprey in focus. Given the focal length and the distance to the shore, it was enough.

Note, I usually shoot in Aperture Priority mode when background blur is important. This lets me choose the aperture most appropriate for the look I want and lets the shutter speed fall where it will. If I need a faster shutter speed I can then open the aperture further (unless it’s already open all the way) or boost the ISO.

It was a very windy day, so things like the osprey’s feathers were moving. And I wanted to be able to capture the osprey if it flew from the nest. This meant I needed a fast shutter speed. I was shooting with a wide open aperture, which would help give me a faster shutter speed. To increase the shutter speed further I boosted my ISO to 500 (200 is the base ISO for the camera I was using). This let me shoot at a shutter speed of 1/1250 sec.

To sum it all up, I shot at 1/1250 sec, f/8, at ISO 500.

Equipment

I didn’t have my longer lens with me for this shoot, but I did carry along my 70-200mm f/2.8 and a 2x teleconverter. This is how I reached 400mm. The 2x does slow things down, causing slower focusing, and giving me a maximum aperture of f/5.6 instead of the f/2.8 of the lens (2 stops slower). But this combo is smaller and lighter than a larger lens and does give me some versatility allowing both the 70-200mm and 140-400mm ranges. I was happy with the compromise for this trip.

Note, the 2x teleconverter only works with some lenses, so be sure it works with yours before you purchase it.

Nesting Blue-Gray Gnatcatchers by Todd Henson

There are times when the trees in some parks are filled with the sights and sounds of Blue-Gray Gnatcatchers. These are small birds with a blue-gray head and back and a white underside. Their call has a lot of volume for a bird so small, and it matches their bravado, as they don’t seem at all afraid of people.

The photos in this post were created over a two day period when I was fortunate enough to watch a pair of gnatcatchers building a nest on a tree limb very close to the trail. The nest was perfectly situated to be lit by the early morning sun when it wasn’t hiding behind a cloud. This combination of great location and nice lighting enabled me to create some decent images of these fantastic little birds.

I found it an absolute joy watching this pair. They would fly away, looking for small pieces of lichen, bark, grass, or spiderwebs, then return to add their find to the nest. They use the spiderwebs to hold everything together. Click on the images for full-screen views, where you can see the lichen and spiderwebs woven through the nest.

Take another close look at the photos to compare the male and female. You can tell them apart because the male has a black eyebrow, whereas the female does not.

Blue-Gray Gnatcatchers are one of the many species I look forward to each Spring. What species do you look forward to?
