Critter Cam | February

The trail camera was out for a couple of days between rain and snow events. There always seems to be plenty of traffic. The camera was set to take 3 images when it detected motion. One or two of the three were sometimes good for sharing here. Some critters move fast and are just a blur. Click on galleries for larger versions.

Raccoons are always making the rounds.

Deer are plentiful all over town and on this path.

Grey squirrels are everywhere.

Possums are plentiful. One image is enough.

Cardinals are a favorite with their red coats and black trim.

Hummingbirds vs Shutter Speeds

Our feeder hangs not far from the front window. The tiny Ruby-throated Hummingbirds come and go quickly. Sometimes there are aerial duels. Wasps and hornets are carefully avoided by the little birds. I hear the birds swoop by me as I put fresh sweet water into the feeder. They have a wingbeat rate of around 50/sec (50 hertz). It is a little lower frequency than the 60 Hz hum of electric current signals I sometimes hear on audio equipment. Here is a link to an audio recording by David Eberly of two Hummingbirds near a feeder. Turn up the volume.

I was curious how different camera shutter speeds would capture the wingbeats. The camera was set on a tripod, focused through the window, and zoomed in all the way. A remote shutter let me get shots without camera shake. This first image used ISO 100 and shutter speed of 1/125 sec. Lots of blur. Even the tail feathers are blurred.

A Sand County Almanac

Over the years, this book by Aldo Leopold has been recommended by many as a good read. I was born and raised only 30 miles from his hometown. My farm life and closeness to nature were strong influences on how I saw the world. A month ago while browsing a used bookstore, I found this copy of his book and decided it was time to read it. I am so glad I did. Leopold’s reflections on the natural world and our place in it fit squarely with mine. If you have not yet read the book, I encourage you to do so.

Crows vs Bald Eagle

Lots of commotion from the Crows this morning. Several of the them were scolding an immature Bald Eagle in the tree right behind our house. It is a BIG bird. It didn’t seem bothered. We have a lot of Bald Eagles around here. They congregate on the Iowa River below the dams to grab fish. It flew away and all was quiet again.

Chickadee Nest

One of our favorite birds all year long is the Black-Capped Chickadee. They busily flit to and from the feeders. They grab a sunflower seed and hold it down on a branch with their feet while they peck it open. Then, it is back for more. We have never seen where they nest and raise their young, until this year.

A few feet from our bedroom window is a sad broken cherry tree. It has suffered broken limbs from branches that have fallen from taller nearby trees. A derecho storm last August nearly put an end to it. Yet is persists. This spring, two Chickadees were going in and out of a hole in the trunk. We wondered if they might nest and raise some young.

It seems they are doing that. Video recorded for about 15 minutes was edited to include these brief highlights for about a minute and a half. The final 30 sec was slowed to make it easier to follow the action. Watch when the bird exits at the end with something in its beak. Can you guess what that was?

Hummingbirds At The Feeder

Ruby Throated Hummingbirds are marvelous tiny creatures. They arrive in the eastern half of the U.S. in the spring from over-wintering in Central America. We keep track of their progress toward eastern Iowa with Hummingbird Central. Users input the date of first sightings in the spring. Some hummingbirds fly non-stop across the Gulf of Mexico for hundreds of miles. Wings flap an average of 53/sec. They flap up to 3 million times during the long flight.

They will be departing our area by late September. We will miss them. Here are an adult male and an adult female borrowed from the All About Birds Macaulay Library.

Eggs in the Phoebe Nest

Update: Under the blue divider is the original post about our new Phoebe neighbors. They built a nest under our deck as pictured at the end of the original post. I noticed one of the birds sitting on the nest a few days ago and wondered if there was a way to see the eggs. Seen from above on the deck, the nest is under the X. I quietly bent down and was able to barely see through the 1/4″ crack to the nest.

I placed my phone over the crack and turned on the camera. The lens is tiny and was able to peer through to the nest. What a pleasant surprise.

Original: We enjoy the usual avian visitors to the woods behind our house. There are cardinals, chickadees, nuthatches, woodpeckers, flickers, etc. who are year-round residents. Others are passing through during migration in fall and spring. This year, we have the nest of an Eastern Phoebe Sayornis phoebe under our deck for the first time. We hope it proves to be a good location for them so we can monitor the progress of their young.

Backyard Birds | Cooper’s Hawk

When Jim and I looked for a different home more than a decade ago, one thing Jim insisted he wanted was a view to the west. Having grown up on a midwestern farm, he learned to love the broad horizon, with its window on the setting sun and on incoming storms. What we actually got, though, is quite different from that. Instead, we have trees nearly touching our house on the west side. With summer’s leaves unfurled, the view beyond our property is completely obscured.

My view to the west, late spring, early evening.

We can’t see oncoming storms, but we do have yard birds. If you read the descriptions in bird books or at one of our favorite sites, All About Birds, you would see that most of our birds like the margins between woods and grasslands. They find familiar territory here.

Some of our birds are seasonal, migrating to or through the area, while others are around all year. Recently Jim posted about a pair of Eastern Phoebes that are nesting under our deck. The phoebes are new to us, though this is within their summer region.

As I worked in the kitchen a few days ago, I hollered at him to get his camera. A Cooper’s Hawk was perched on the tree out back. Usually when we see them, they are too far away too see clearly, or they are swooping through, intent on catching a meal. But this one was still, and at my eye level. It also was directly above one of our bird feeders. No, it doesn’t find its meal in the feeder; it finds it at the feeder. Coopers eat smaller birds and rodents. Once we watched one land on, firmly grasp, and fly off with a struggling squirrel. Surprisingly, they’re not terribly big birds, only about the size of a crow. Click any photo to embiggen.

Besides the great photos, Jim also was able to get this short video.

We don’t have the setting sun, but we have an ever-interesting assembly of birds out our window.

Prairie Burn | 12 April 2018 (+4 mo update)

Seventeen years ago, friends of ours moved from their in-town home to a 5 acre property several miles out of town. They built a beautiful prairie-style house and converted 4 acres of their alfalfa field front yard into a mixed prairie like it was 200 years ago. Native grasses, wildflowers, and trees were planted and a small pond was formed. The plantings grew well in the rich Iowa soil. Wildlife returned. Bird species grew in number. Kestrels nested in the box above the open space. Waterfowl visited the pond. They kept paths mowed to allow easy access to parts of the prairie visible in this satellite view.

Recent year Google Maps view. Pond lower left. House upper right.

Only one thing was missing from their prairie. They needed a fire. Much dry vegetation was on the ground built up from years of growth. Certain desirable native species were crowded out by less welcome grasses or weeds. They hired a crew to burn off the dead vegetation. The burn must be a carefully controlled prescribed fire carried out by an experienced team. Fire was a natural and essential event on the prairies in the past. A thorough discussion of prairie burns can be found at The Prairie Ecologist. The author, Chris Helzer, is The Nature Conservancy’s Director of Science in Nebraska.

Before the burn was started, I stood next to the house in the image above and recorded video of the scene toward the south, then panned around to the west and northwest. It was a calm day with gentle breeze in the direction of the pond.

The fire team of four arrived in the late afternoon and walked around the property to assess their strategy. You don’t just toss a match and hope for the best. That is how prairie burns get out of control. There is a procedure used to keep the fire under control.
