Buteo

red-tailed hawk Last week we talked about Accipiters, one of the two genus' that make up the hawk family. This week it is time to explore the rest of the hawks which reside in the Buteo genus. Buteos have long wings and relatively short tail which are perfect for soaring. Most Buteos hunt by ambushing their prey, preferring not to waste their energy in a chase. They mainly eat small mammals but they are usually generalists and opportunists and they will also eat reptiles, amphibians, birds, and carrion.

Every day on my way to and from work I can count on spotting several red-tails perched on the light poles on the side of the freeway. Red-tails are a border species meaning they often live on the edges of wooded areas and open fields. They will nest in the safety of the woods as well as roosting there at night but they need the open fields to hunt in. Roadsides are good hunting habitat since there are not many large trees in the way, there are usually a good number of rodents around, and the grass is typically cut shorter making it easier to find their prey. The bird in the first pic is a young red-tailed hawk.
red-shouldered hawk Some of the other Buteos that we see here in Minnesota are broad-winged hawks, second photo, and the red-shouldered hawks, above. The broad-winged hawk is the smallest of the Buteos in this area. Their smaller size allows them to live and hunt in wooded areas that the bigger Buteos have a more difficult time navigating. Each year these birds migrate down to South America for the winter. They migrate over Minnesota in groups called kettles that sometimes consists of thousands of birds. The red-shouldered hawk is slightly smaller then the red-tail with a forty inch wingspan. They are found in the south eastern part of the state, usually near a wetland, and are much less common then the red-tail or broad-winged hawks. We also see Swainson's hawks, mostly in the south western part of the state, and rough legged hawks, that migrate into the area for the winter.

Broad-winged Hawk

Hawks are broken down into two different families, buteos and accipiters. Buteos are what most people think of when they think of hawks. They have long rounded wings and often seen soaring on thermal air currents. Since accipiters are hawks they also have rounded wings but their wings are shorter and their tails are longer. This gives them more maneuverability which they need since they are primarily bird hunters.


One of the smallest members of the butoe family is the broad-winged hawk. These stocky hawks are usually found in deciduous forests in much of the eastern half of North America. I found this broad-winged hawk near the Old Cedar Bridge in the Minnesota Valley NWR.
Broad-winged hawks eat much of the same prey as their larger cousin the red-tailed hawk, this includes mammals, reptiles and amphibians, small birds and even large insects. Because of their smaller size they are able to get around in and hunt with in the forest usually ambushing their prey by dropping on them from their perch in the tree top canopy.

Broad-winged hawks go through a mass migration each fall, in Minnesota this typically occurs around mid September. Though not really travelling together many travel in the same thermal currents. This phenomenon is called a kettle. they will travel about 60 to 70 miles per day and end up in Central America or the northern portion of South America where they will spend the winter.

Hawk Ridge

After we got back from our Lake Superior boat trip we took a quick tour around Park Point. We did not see much except for a mourning cloak butterfly.

He looked kind of ragged and had a hard time standing so he may have taken a rough flight over part of Lake Superior. I did see butterflies and other insects out of over the lake while we were on the boat.

Since we did not see much we decided to go get some lunch and then head up to Hawk Ridge. It was about 3pm when we arrived and it was still very crowded since it was the Hawk Weekend celebration. We were a bit past the prime raptor viewing time but we did see a nice selection of raptors.

This included a few sharp-shinned hawks, there was a total of 961 spotted that day.Bald eagle and broad winged hawks, 46 total eagles and 4095 broad-winged hawks were counted that day.A lot of american kestrel, 205 were counted for the day.

And a merlin, 5 were seen throughout the day.

To see what other raptors were seen that day, and all the days through the fall migration, check out the Hawk Ridge Hawk Count page.

There were also other activities going on because of Hawk Weekend. These included educational programs, Michelle went to one of these and raptor banding. Those people who sponsored a raptor where able to tour the banding station and were even able to release there adopted bird. This kestrel was not too thrilled about being caught and banded. It even took a bite from the finger of the count interpreter who was passing it to the young boy who had adopted it.

Both survived and the boy was able to release the bird with out incident.

Here is a close up of the kestrel who gives me a look that says, "what the "bleep" am I doing here."

The unique part of the adopt a raptor program at Hawk Ridge is that you bird that you adopt is unique to you. They tell you the band ID number and notify you and give you information when your bird is recovered. I would have adopted one but it was already too late to get to release the bird that day so I will need to adopt one on my next trip up.

While we were waiting for raptors to fly by there was plenty of wildlife to photograph. There were quite a few black-capped chickadees around.

They were joined by a group of white-throated sparrow, there may have been some white-capped mixed in.They were competing with the rodents for seeds that the volunteers had spread on the ground.This chubby ground squirrel had no problem coming out to get more then his share of seeds.The chipmunks were not as daring. They would make quit raids, grab what they could and then retreat back to the brush.

We stayed for about an hour and a half but then decided to get going. We still had a couple hour drive ahead of us and we wanted to get home at a descent time so that we could eat dinner.

More shots from my Canon 40D

On my way home from Dodge Nature Center I had the fortune of coming across a broad-winged hawk hunting from the power lines on the side of the road.I got a couple of picture then he flew a bit down the block and landed on the power lines again.

I stopped to get a few more pics with a nice blue sky background behind him. He was pretty cooperative and let me get my car fairly close in order to shot him. I did not want to spoil his hunting so I got my pics and then let him be.
Broad-winged hawks migrate further then most raptors do. Their winter range is from Mexico to southern Brazil. When migrating they often travel in large flocks called kettles. A great place to observe kettles of broad-winged hawks migrating, is Hawk Ridge in Duluth, Minnesota. Michelle and I will be in Duluth on September 22 for a short birding boat tour on Lake Superior and if the weather is nice plan to stop at Hawk Ridge afterwards to see if we can witness a kettle or at least do a bit of raptor viewing.
