SHARPI STRUCK AGAIN


Sharp-shinned Hawk

We received quite a bit of snow today, the first time this season worth to talk about. The numbers of birds visiting our feeders increased with every snow flake that hit the ground. The first thing I saw this morning while looking at the birds was our Sharp-shinned Hawk sitting in the snow of the driveway. I knew immediately what had happened because I witnessed it before at other times. The hawk had caught some prey midair and just rested with its kill for a moment. When the Sharpi finally took off I saw a small bird in its claws, probably a poor junco or a finch that wasn’t fast enough to hide.

The photo above is not from today but it lets us imagine what a fierce predator the Sharp-shinned Hawk is. With their distinctive proportions, long legs, short wings, and a long tail they can move in an acrobatic manner between trees and at top speeds in pursuit of small birds or mice.

RETROSPECTS 2023 - #6


Sharp-shinned Hawk, Little Maquoketa Valley, Iowa, February 2023

This is the raptor every other bird pays utmost attention to in our woods, the Sharp-shinned Hawk. When all the woodpeckers or nuthatches freeze motionless and the sparrows and finches disappear suddenly, we just know the ”sharpy” is somewhere around here. Sometimes we don’t see him or her but all the birds obviously do and immediately adapt their behavior. They are able to move very fast between the trees without hitting a branch and can strike with surprise. I have seen a Sharp-shinned Hawk taking a Northern Cardinal down mid air. What follows is usually not very pretty but nature’s rule requires that they all have to eat sometime for survival…

In early February this hawk spent more than half an hour in great light near our bird feeders and the only difficulty to overcome was to find a position with the camera that had an unobstructed view between the trees. It was just another great moment in 2023 and worth to mention again.

SEEKING ITS CHANCE


Sharp-shinned Hawk

Here are two more photos from last weekends’s shooting in the “front yard studio”. Our Sharp-shinned Hawk didn’t care about me standing on the porch at all and gave me 36 minutes to make new pictures while he was waiting for a chance to catch some prey. As already mentioned, the light was perfect that day. The biggest challenge was finding a spot with an unobstructed view. The bird moved several times between different trees at the edge of the woods. It finally tried to hunt down a woodpecker but had to leave hungry this time.

SHARPIE’S STRIKE


Sharp-shinned Hawk after making a kill

A short glimpse outside the window this late afternoon told me that a raptor was around because all the birds were gone. Well, wait a minute, except for one! It was our Sharp-shinned Hawk who got a hold of a woodpecker. There wasn’t much left of the bird and I’m still not 100% sure if the hawk caught a Downy or one of the larger Hairy Woodpeckers. The size of some feathers make me believe it was the latter.

I grabbed the camera quickly and opened the window silently. The picture is cropped to about DX size because I had to shoot through the legs of a bird bath installation in the front yard. The Sharp-shinned Hawk ate pretty fast but lifted its head from time to time.

The key for a sharp shot was predicting when the head is up and at a total standstill, called “peak of action”. The ability to shoot up to 14 frames per second with the Nikon Z6II helps to nail this moment even with just a short shutter burst.

Of course, we like all birds we are fortuned to see here above the Little Maquoketa Valley. It’s sad to see a woodpecker go, but we also know birds of prey, as the Sharp-shinned Hawk, play an important ecological role in maintaining the environmental health of their natural habitat. As apex predators they remove sick, old, and weak animals from prey population and keep prey species and mesopredator populations under control.

THE ELEMENT OF SURPRISE


John Deere Marsh, Mississippi River, Dubuque, iowa

The trees at John Deere Marsh, down at the Mississippi River, had a white coating after yesterday’s snowfall. The temperature had dropped quite a bit overnight (-14ºC / 7ºF) and the snow was clinging to almost everything. Part of the marsh is still very dry and doesn’t have much water, due to little rainfall last summer. Normally we wouldn’t see that much vegetation still standing and ice would cover the area up to the tree line. As so often, I document weather and climate related changes but still try to do it with an artistic touch.

I focussed on the dead tree in the middle ground with a wide open lens, knowing that foreground and background would render just graphic impressions out of focus, when suddenly the element of surprise came into play. While looking through the viewfinder and zooming with my feet, back and forth, left and right, a male Northern Harrier came buoyantly gliding into the frame. I can’t think of another bird of prey, except for certain owls, that is a better representative for the marsh and wetlands than the Northern Harrier. Their owl-like facial disk helps them with directional hearing to locate their prey. At this time of the year they rely mostly on rodents and birds

The Nikon Z6II is capable to combine multiple shots into one picture but the time was way too short to make a change in camera settings of that magnitude. However, I made three clicks, with the second one the photo you see here. In Adobe Photoshop I copied just the bird from the two other images into the final picture, at the same spots as in the originals. Now you have an idea how this story developed within one second in my viewfinder.

The detail obsessed viewer may see more in the photo. At the tree line in the back is a huge Bald Eagle nest. An eagle is guarding it and maybe we see them breeding again next year at this location.

NEWS FROM THE BARRED OWLS


The canopy of all the trees around is closing very quickly now, making it harder every day to get a clean shot of our Barred Owls. As you can see in my second picture below from two days ago, I finally had a chance to photograph the owlet. I’m not happy with the picture because I had to employ a speed light as my main light source but I saw its silhouette against the evening sky and the only way to make the click for this documentary shot was to use flash. It was so dark already that I’m surprised that I got away with a halfway sharp image.

A day earlier, last Monday morning, I witnessed some drama in our woods. I heard and saw both adult owls and they were celebrating a successful hunting effort. One of them had a bird in its talons and as far I’m concerned it may have been a young Blue Jay. While it flew out of sight to a different tree the other owl sat kinda proudly in best morning light in a tree across from my office. The picture above was made shortly after while a Blue Jay attacked the owl and tried to scare it away. I have seen this behavior before. The Blue Jays are pretty fearless and hit the owl with their wings, hoping that this predator goes away, but in this case it was obviously too late.

FIVE RAPTORS


CYSCO, Harris’s Hawk, hatched in captivity in 1994, excelled as a falconry bird, and came to the Schlitz Audubon Center after retirement. ------------ 

It was fun at the 30th Annual Bald Eagle Watch in the Grand River Center of Dubuque yesterday. The event that celebrates the American Bald Eagle had a very good turnout with people of all ages. We had lots of good conversations with visitors at the information desk of the Dubuque Camera Club and the other participating organizations have been very busy as well. The highlight for many guests was without any doubt the live bird program, presented several times during the day by staff and volunteers of the Schlitz Audubon Nature Center, Milwaukee WI. The program was great education, not just for all the kids who got involved by Sara, who did a very good job of moderating it.

BARON VON SCREECH, Eastern Screech Owl, lost his right eye in a car accident.

It was allowed to take pictures, even with flash lights, but I decided to use just the ambient light for making some images of the raptors and the people who showed them to the audience. All photos were made handheld at f/4 between 1/20s and 1/40s. The ISO was cranked up to 1600. Shooting indoors is not my usual thing to do and dealing with white balance in very dim incandescent light had its challenges. The presenters moved around to give everybody a chance to have a close-up view of these beautiful raptors and the birds themselves move as well, with other words, not an easy task to get a sharp image.

CUTRIGHT, Peregrine Falcon, a retired falconry bird.

All seven birds of prey that were introduced to the audience (I only show five of them) are unable to make a living out in the wild for various reasons. Since I didn’t make notes (too busy fiddling with the camera 😉), the information about each bird under the photos is from the website of the Schlitz Audubon Nature Center. https://www.schlitzaudubon.org/education/raptor-program

TSKILI, Great Horned Owl, was stolen from her nest by a human who wanted her as a pet.

VALKYRIE, Bald Eagle, Was left by her parents earlier than normal. She did not have the hunting skills to survive in the wild. I like this photo because it shows the enormous size of an eagle, next to Sara, the main presenter of the program.

NATURE CLICKS #364 - NORTHERN HARRIER (FINALLY!)


Green Island Wetlands, Iowa  --------   

I don’t know how often I have aimed my lens at a Northern Harrier in the Green Island area over the years but never came back with a result that was more than a “private documentary shot”. This hawk has hoaxed me many times but a week ago I finally made a couple shots that can be shown in public. No, this is not the photo I have in mind, there is a lot of room for improvement, but hey, the jinx is broken…😉

Northern Harriers use their sense of hearing to help locate their prey, which is unusual among hawks. Their owl-like facial disk helps with directional hearing.

NATURE CLICKS #253 - DOWNY WOODPECKER


Nikon D300s, Sigma 50-500mm / f4.5-6.3 APO DG HSM, Nikon SB800 speed ligh

Every bird goes on high alert here in our woods if a bird of prey shows up. They either fly away panicky or they just freeze absolutely motionless, like this Downy Woodpecker just outside our window. A Sharp Shinned Hawk hunts here quite often, and even if we can’t see the predator always, we know it is around by just watching the other birds behavior.
