Northern Hawk Owl

 The northern hawk owl is an unusual owl that is found through out the boreal forests of the northern hemisphere. They are the only members of the genus Surnia in the world. There are three subspecies. Two subspecies are found in the forests of Europe and Asia and the third subspecies is found primarily in Alaska, Canada and parts of the northern United States. Northern hawk owls are unusual in that the are more diurnal, active during the day, then most other species of owls.

Like most owls the northern hawk owl remains on its breeding grounds year round. The habitat that they prefer is boreal forest, which is primarily coniferous. There they hunt a variety of prey including small mammals and birds. Their primary prey are voles, which are a type of field mouse. They usually use their acute vision to find their prey, although during the inter they often use their hearing to locate prey burrowing under the snow. During some winters food is scarce, either due to a crash in the prey species or an over abundance of owls raised that year, and the owls head south in search of prey. This is usually the time that we see these birds, most of which are immature birds who have just left their parents territory. These birds were photographed at the Sax Zim Bog in northern Minnesota.

 Northern Minnesota is a great place to look for northern owls during the winter. Often the population of prey species in Canada gets low or the number of new owls that are successfully hatched and raised is higher then normal and so during the winter the owls head south. Probably our most frequent visitor over the past 5 years has been the northern hawk owls. This species of owl is primarily diurnal, which means that they are active during the day which makes them easier to locate. This winter there appear to be less northern hawk owls around northern Minnesota then usual but many more boreal owls have been spotted this year.

Owls

Continuing on with this weeks birthday celebration we had two owls that where like book ends in the 2012 calendar. The January photo, above, was of a northern hawk owls. These are owls that typically live in boreal forests. We see some in northern Minnesota, especially in the winter time when some of the younger birds migrate south in search of better hunting. They are diurnal so they are often active during the day which makes them much easier to photograph. I photographed this bird at the Sax Zim Bog in March.

December featured this little saw-whet owl. Saw-whets nest up in southern Canada but migrate to the northern United Sates during the winter. At Hawk Ridge in Duluth, MN they often catch and band hundreds of these birds as they migrate south in October. A few usually end up in south eastern Minnesota over the winter and if we are lucky we get a chance to see one. This bird spent a couple of days in the backyard of a Twin Cities birder. he was nice enough to let the rest of the birding community come into his yard to get a peak.

Hey, Hey, It's our B-Earthday!

Four years ago today I began this blog with a post that said:

Welcome to my new Ecobirder Blog

In honor of Earth Day 2007 I have started my first blog. The purpose of this blog will be to share my love of the environment, wildlife, and birding with others who share these interests.

A couple days later I posted my second post which included 3 pictures of a great horned owl nest that I was photographing at Wood Lake Nature Center. I had hoped to put these pics into my first post but I was very new to blogging and was still trying to figure things out. I wanted to start the blog on Earth Day, since the blog has a lot to do with the earth, nature and environment, so I decided to make an announcement post on Earth Day to start the blog and begin posting the pictures when I was ready.

I figured that for this B-Earthday we would invite a bunch of owls back to help us celebrate. I photographed this little eastern screech owl near Minnehaha Creek in south Minneapolis in December of 2009. I heard about the owl of the MOU list serve but it took me several trips before I finally found it out sunning on New Years Eve. I guess that proves what a nerd that I am, celebrating New Years Eve out freezing my butt off taking pics while everyone else is out getting ready to party.
2009 was a pretty good year for taking owls pics. While I was participating in the Redwing Christmas Bird Count in December of 2009 we decided to quit and head back up to the Twin Cities early. We had heard about a long-eared owl that had been spotted in a park in St Paul during the Bloomington count the week before so we decided to see if we could locate it. It took us a while but we did find the owl. Unfortunately dark comes early in December so the picture is not as good as I would have liked but you don't often get to be picky when it comes to owls.

In 2009 we took a side trip to Idaho during our Yellowstone vacation to participate in the first ever Snake River Birds of Prey Festival. Since we did not have much time, Yellowstone was calling, we only signed up for a field trip on borrowing owls. The field trip was great we had owls out in the field to photograph and even got to open up some man made burrows to check out burrowing owl chicks. Definitely one of the highlights of that year.

I have been fortunate over the years to be able to observe several great horned owl nests. A hawks nest that was taken over in Lakeville, MN has been the most productive for getting pics. Great horned owls have produced young in this nest in 2008,2009 and again this year. In 2009 they raised three young that began to branch, walking out on the branches before they can fly, in April.

So far 2011 has been a pretty good year for photographing owls also. Although I have had the opportunity to photograph northern saw-whet owls during the owl programs at Hawk Ridge over the years, I have not had the opportunity to photograph one that was not trapped for banding until this year. Back in February a saw-whet decided to perch, for a couple of days in someones back yard in Bloomington, MN. Fortunately the home owner was a birder and he got the word out about the owl in his back yard. A lot of people showed up over the next couple of days, myself included, to get some great photos

This year I made a couple of trips up to the Sax Zim Bog during the winter, as I do most every year. The first trip was for the first ever Brrrdathon that was held in January. As often happens in January in Minnesota the first day of the Brrrrdathon was complicated by a snow storm that dropped about six inches of snow in the area. Fortunately the next day, Saturday, the weather turned sunny and it was a great day to be about taking pictures of wildlife. Since I was spending one more night in a hotel in Duluth I stayed out in the bog until it got dark. I was rewarded when a pair of great grey owls began to hunt along the road at dusk. Since great grey owls are crepuscular, active at dusk and dawn, they can be tough to photograph.

In comparison northern hawk owls are diurnal so they are active during the day which makes them much easier to photograph. I saw northern hawk owls on both my trips up to the bog, as I have in most every year. I took this pic on my second trip at the beginning of March. This hawk owl seemed to be very used to people so it was not very nervous about my presence. As such I was able to get some really nice pics.

So another year of blogging has come to an end and a new one begins. This is the 1502 post that I have done in the four year. I have managed to post every day for most of the past three years. I really hope that you have enjoyed coming here and have taken something away from my pictures and writings. If I manage to make it another year I will have to do something really special for my 5th B-Earthday. I have updated the slide show on my side bar, the old one was getting a bit tattered and frayed, and I hope that you enjoy it. I hope to see you all here over the next year and invite you to join in the big party one year from today.

A Day in the Sax Zim Bog

For the past month I have been tyring to get back up to the Sax Zim Bog area to take some pics. I usually try and get up there a couple of times each winter because it is one of the best places around to see some of the species that usually live up in the boreal forests of Canada. I made my first trip up in January for the Brrrrdathon but because of weather and schedule I was not able to make it back up until last week. Since I had a vacation day that I had to burn I decided to take off last Thursday and head north.The weather on Thursday turned out to be quite nice. Except for some clouds around noon, the skies were pretty clear with temps up into the 20s. My first stop when I arrived was to the feeding station on Admiral Ave. I have always found this to be a great location for finding many of the wintering passerines. On this trip the feeders were dominated number wise by common redpoll. When I was up in January the only place that I found redpolls was at some of the feeders in the Meadowlands but on this trip they seemed to be everywhere. A couple of rare hoary redpolls have also been reported but I did not see any redpoll that appeared like it might be a hoary.

In contrast to the redpoll numbers were the numbers of pine grosbeak. In January there were large numbers of pine grosbeak around the bog. You could find a half dozen or more at almost any feeder in the bog. On this trip however I only spotted a couple females at the Admiral feeder and no other pine grosbeak anywhere else.

There were still a couple of boreal chickadees hanging around the Admiral feeder. They would come in and feed for a little bit and then disappear back into the bog. Forty five minutes to an hour later they would fly back in to the feeders, eat and then disappear again. While I was there I pointed them out to several other people who were looking for them because they were a life bird.

There were also a lot of gray jays at both the Admiral feeders and the feeding station on Arkola. Gray jays are very clever birds and not very afraid of people. On a couple of occasions I was afraid that one of them would fly though my open car window at Arkola.
After the two and a half hour drive and spending a couple hours in the car at the feeders I decided it would be good to get out and stretch my legs. So I put on my boots and headed off in to the woods off of McDavitt Road. This is usually a good place to find black-backed and three-toed woodpeckers. As I walked into the woods I could see signs that there were woodpeckers in the area. Black-backed and three-toed woodpeckers typically peel the bark off of the trees instead of boring holes in the wood like most other woodpeckers do. So I listened for their distinctive peeling sound and found a male bird at work deep in the woods.

It was a lot of work walking through the deep woods and thigh high snow to get the woodpecker pics so I decided to walk along a path for a while. This was fortunate because a little ways down the path I came across a northern hawk owl. Northern hawk owls are one of the few owls that are most active during the day, diurnal. The owl was perched over an area that had recently been used for logging and was probably hunting rodents that lived in the remaining wood piles. Later on I looked for great gray owls in the same area, I saw two on McDavitt in January, but on this trip I did not have any luck with great grays. This might have been because I did not want to stick around too late since I still had a two and a half hour drive to get home.

In Flight

The northern hawk owl got its name because it looks and acts more like a hawk then other owls do. Hawk owls have more pointed wings then most owls which enables them to fly more quickly then other owls. They are mostly diurnal, active during the day, and use their sence of sight to find prey more then their hearing. I photographed this northern hawk owl as it was hunting, up at the Sax Zim Bog in January.

1st Annual Brrrrdathon

Last weekend I headed up north for the first annual Brrrrdathon. This event was sponsored by the newly created organization The Friends of Sax Zim, formerly Bird Nation, to raise money for an eventual visitors center in the Sax Zim Bog. Like any outdoor event held in Minnesota in January weather played a major role. Shortly after I arrived in Duluth on Friday the snow began to fall, which made photographing wildlife, not to mention driving, very difficult.

As I sat in my hotel room Friday night I was worried that the trip would be a waste of time due to the weather but when I woke up Saturday morning the skies where clear and blue. After digging my car out of the snow I headed out slowly to the bog. The city plows were already out working but the road conditions were still not very good, especially when I got to the back roads in the bog.

Despite my concern over the roads I was excited about the number of birds that I spotted as I travelled to the bog. The end of the storm seemed to bring the birds to life and many of them fluttered from tree to tree looking for food. As I entered the bog area a bald eagle soared from his perch to greet me.

The first place in the bog that I headed to was a feeding station that had been set up on Admiral Ave. Admiral had not been plowed at all but I was able to make it through travelling down the tracks of others who had already made their way down the road. A feeding station has been set up in this location for years and it has always been good for attracting northern species including boreal chickadees. When I arrived at the feeder there was already a pair of boreal chickadees there as well as black-capped chickadees, pine grosbeaks, red-breasted nuthatch, and downy and hairy woodpeckers.

After shooting at the Admiral feeder for about an hour I headed over to McDavitt RD, which is another location that many of the northern species have been seen. About half way down McDavitt I found a path in the snow that went back to a small feeding station that was located in the woods. I decided that I could use a little exercise so I through on my winter gear and headed out down the path. It did not take long before I located a pair of black-backed woodpeckers. I was excited because black-back and three-toed woodpecker sightings have not been as common this year as they have in the past. Unfortunately to get the angle I needed to get decent shots of the bird I did have to wade through waist deep snow. It was worth it though, don't you think?

The main attraction at Sax Zim are the northern owls. The Sax Zim Bog is a mix of state, county and private lands, which includes the Cloquet Valley State Forest, Whiteface River State Forest and the Sax and Zim Wildlife Management Areas. The habitat consists mainly of conifer bog, spruce, tamarack and white cedar. This particular habitat is very attractive to northern owls that come down from Canada in the winter in search of food. The most common type of owl seen during the winter is the northern hawk owl. I found this northern hawk owl perched in a tree not far off of Mcdavitt. Since northern hawk owls are mostly diurnal, active during the day, they are one of the easiest owl to photograph.

As the sun went down on Saturday night many birders began their search for the most prized bird in the bog, the great grey owl. Great grey owls have not been seen with any regularity in the bog since 2005, when there was an irruption of thousands of birds which came down from Canada. This season there have been more sightings then in the past few years but it still seems to be hit and miss. The fact that they are crepuscular, hunt at dusk and dawn, also does not help, especially if you are looking for pictures. Fortunately around 4:30pm I found some people who had spotted a pair of these owls on McDavitt Road. I got a few pictures in the low light and then just watched them hunt until the sun went down.

Owls of 2009

In 2009 I had a good year for photographing owls. Through out the year I photographed 6 different types of owls, as well as a seventh type at the owl banding at Hawk Ridge. Three of the owls made it into the calendar. The first owl that I photographed in 2009 was this northern hawk owl up at the Sax Zim Bog. Northern hawk owls are great to photograph because they are usually diurnal, active during the day, which makes for better pics. I was also able to photograph a great gray owl on that trip but it was at dusk so I had to turn up the ISO on the camera which made it too grainy to blow up big enough for the calendar.

In late winter and early spring I was fortunate enough to be able to observe and photograph two great horned owl nests. The first one was in an old hawks nest that was located in a field across from a small strip mall. I had watched these owls raise a brood in 2008 and they were back in 2009. I began to watch the nest at the beginning of February, the female was already on the nest incubating her eggs, and visited regularly until the three chicks that they hatched fledged. In early May I learned about the second nest in a local county park. The nest was located in the hollow of a dead tree, which was cool because I had only seen this type of nest from a distance in Yellowstone prior to that. The chicks fledged soon after I found the nest but I was able to get a few good pics before they left including this one that ended up in the calendar.

Burrowing owls can occasionally be found in the western portions of Minnesota but it is infrequent at best. This particular burrowing owl was photographed while on a visit to the Snake River Bird of Prey National Conservation Area in Idaho. We made a quick side trip to Snake River during the Snake River Bird of Prey Festival as part of our Yellowstone vacation. We did not have much time but we did sneak in a field trip where we went to man made burrowing owl dens and got to photograph both chicks and parents.

I also had the opportunity to photograph a eastern screech owl and a long eared owl but it was too late in the year to get them into the calendar.

Winter Birding Part 4: Sax Zim Bog

One of the best places to bird in Minnesota during the winter is the Sax Zim Bog Wildlife Management Area. The bog is located in northeastern Minnesota not far from Duluth.

The main attraction of the bog are the owls that come down from Canada during the winter. As food sources up north of the border decline, due to winter weather, owls head down to the bog in search of prey. The most common northern owl to see is the northern hawk owl, above, which is a diurnal owl, meaning that it is active during the day which makes it easier to find. Other northern owls that sometimes visit the bog include great gray owls and boreal owls.

Besides the owls there are some other colorful species that can be found in the bog during the winter. One of the most common is the pine grosbeak, pictured above. Male pine grosbeak are red and gray while the females are more of a mustard color. Evening grosbeaks and white-winged crossbills can also be found, though they are not as common as the pine grosbeak.

Northern finches can usually be found around feeders. The numbers of these birds that visit the bog changes each year depending on the amount of food available back in their summer range. Last year there was quite an irruption of northern finches with pine siskin, pictured above, and redpoll being spotted all the way down in Iowa. This year I spotted very few northern finches, only a few pine siskin and one redpoll on this trip.

There are always plenty of chickadees around. Even though they are very common it is important to keep your eyes on them because you never know when a boreal chickadee might show up. These are another resident of the boreal forests up in Canada who will sometimes come down to Minnesota looking for food, but these little guys are not looking for seed. They are insect eaters so they are looking mostly for protein. So for the past few years several local birders in the area have attached parts of deer carcasses to trees in different locations through out the bog. This is a good source of food for many birds, especially the boreal chickadees and it also gives birders a place to look for these special birds. Unfortunately this year a local resident complained that the deer carcasses were attracting wolves, despite evidence to the contrary, and the DNR took them all down. This looked like it was going to be the end of one of the best places to photograph birds in Minnesota during the winter until a compromise was reached. The deer would no longer be allowed on public land, however seed and suet were allowed. So feeders went up in many key locations and the birds continued to come in to eat.

I never did see any signs of wolves. There were no tracks around the feeding stations and the carcasses were never torn down. The closes thing to a wolf that I ever spotted in the bog was a red squirrel but I don't think that he was causing too much trouble.
