Went looking for Short-eared Owls at Rollins Savanna the other night. We weren’t the only ones looking around. Found this friendly juvenile White-crowned Sparrow in the parking lot.
No luck on the Short-eared Owls, but the sunset did its best to make up for it.

This post is really about a specific niche of bird blogs, but I couldn’t pass up commenting on the bird blog news that has been boggling my mind in the past few weeks.
Seriously, I picked a lousy month to fall behind in my blog reading! October has been an exciting month for bird blogs, to put it mildly. In late September, the Nature Blog Network asked the community for input on expanding the network, and in early October they introduced two new team bloggers. More big changes are on the way. Big recent changes at the ABA include the announcement of a new president on October 4, and a new, multi-authored ABA Blog. On October 18th, the three regular bloggers at 10,000 Birds announced the addition of several beat writers to the team. On October 20th, the multi-authored BirdingBlogs.com officially launched. And then, yesterday, the “mega-blog” North American Birding officially launched, although contributors have been posting for a few weeks already.
With all of these new superblogs added to my reading list, I may never catch up. Back to the subject at hand — for this post I wanted to highlight some more neat bird banding blogs that I’ve been following in my quest to learn more about the technicalities of banding birds. Science learns a lot about birds from banding schemes, as mentioned in my last post (which obviously doesn’t even begin to scratch the surface). And I have been learning a lot about birds, and the ins and outs of banding, by following bloggers who band. These are some of the banding-themed blogs that I’ve been following for a while.
The WPBO Owls blog primarily covers Saw-whet Owl banding at the Whitefish Point Bird Observatory. They’ve had a good season this fall.
Net Results is a blog from banders at the Rouge River Bird Observatory at the University of Michigan-Dearborn. In addition to banding birds, they are running a study on the preferred seeds of certain bird species. Pretty neat reading.
Minnesota Birdnerd bands birds near Apple Valley, Minnesota. This blogger also frequently posts radar images showing bird migrations. Very cool.
Faab’s Sightings. Faab is a young birder who rings birds in the Netherlands. It’s neat to see the Dutch perspective on bird ringing – and they get some pretty great birds, too.
Rob’s Idaho Perspective. Rob is a masters biology student, and banding songbirds and raptors is part of his field work.
BSBO Bander’s Blog is from the Black Swamp Bird Observatory in northwestern Ohio. This is a banding station I’ve been lucky enough to visit as a spectator a couple of times. I love this blog because it shows lots of closeups of birds and points out unusual field marks and identification techniques. The blogger also challenges readers with quiz birds.

If you search Google for “bird observatory” blog, you’ll find many results (unfortunately, not all of the listed blogs are active). Do you follow any bird banding blogs? Please let me know your favorites in the comments!
Last summer I had the opportunity to volunteer at a (temporary) banding station at Rollins Savanna, a preserve in the Lake County Forest Preserve District. The banding station followed the MAPS protocol, which basically means we were doing a breeding bird survey. We went out approximately every ten days during the summer months. The data will be analyzed over time to look at how the habitat is being used by breeding birds, like this Cedar Waxwing we banded on June 20th.
I was able to join the team at Rollins Savanna after attending a forest preserve banding demonstration in 2009 and talking the MAPS group during their 2009 season. I wanted to learn more about birds and more about the banding process. It was a great experience, I certainly learned a lot, but there is much more to learn. Now that the banding season is over, I’ve been reading more about how bird banding data benefits conservation science, and ultimately the birds themselves.
We learn about how birds age.
We learn about bird migration.
Of course these extreme records are interesting, but a lot of data gleaned from bird banding is about averages and trends. Breeding success data helps land managers determine where habitat restoration or maintenance resources will best benefit the birds. Migration data helps scientists understand changes in bird populations and helps environmental groups working to help birds on both breeding and wintering grounds. If you’d like to learn more about bird banding and data collection, some excellent resources are listed below.

Last Saturday night Arthur and I visited the Sand Bluff Bird Observatory in Durand, Illinois. The banding station is open each weekend during spring and fall migration, and they band a huge number of birds – up to 4,000 per year. The station has been in operation since 1967 and has always been run by a team of dedicated volunteers. Visitors are welcome to observe songbird banding activities, which takes place during the day. Our visit on Saturday night was to see a special, nocturnal bird: the Saw-whet Owl.
Northern Saw-whet Owls are small owls that winter in our region (there have been a few records of breeding Saw-whets in Lake and Winnebago Counties). The birds are banded during migration, when they are lured into mist nets using recordings of Saw-whet Owl calls. The data gathered through banding helps us understand more about these tiny nocturnal owls.
As in other bird banding work, data such as sex, age and condition are measured each time a Saw-whet Owl is captured and banded. Saw-whets can be sexed by comparing measurements like wing chord (the length of an extended, relaxed wing) and weight. Age can be determined by examining the plumage and molt pattern.
The program began with Sand Bluff Master Bander and founder Lee Johnson telling us about the banding station and their work. Since no Saw-whet Owls were found during the first evening net-run, Lee took some time to show us a few of the songbirds that were still being processed at the end of the day. Here he’s showing a Hermit Thrush. Of the thrushes that migrate through the area, Hermits are usually the first to arrive in the spring and the last to fly through in the fall.

It was great to see these little birds, which included a Fox Sparrow and a fiesty Field Sparrow besides the Hermit Thrush. But it did come as a relief when a Saw-whet Owl was found in the nets on the second run of the evening. Notice the high-pitched tooting in the videos – that’s the recorded call of the Saw-whet.

In all, three birds were captured in the nets during the evening. After an owl was removed from the net, it was brought back to the banding station building in a mesh bag. The bird remains in the bag during the banding process.

The main reason for this is to protect the bander’s hands from these:
Sharp and deadly to prey! Saw-whet Owl talons
After banding, the bird is examined and measured, and the data is recorded. The wing feathers are even examined under a black light to help determine the bird’s age.

Saw-whet Owls are extremely docile in the hand, which adds to their already high cuteness factor. Did you notice how calm the bird was in the two video clips above? After data was taken on each bird, visitors were able to have a closer look. Here, Lee shows us the large ear opening of a Saw-whet Owl.

The birds also appear to enjoy having the backs of their heads stroked, as you can see in this short clip.
Earlier in the evening, Lee had asked each visitor to introduce him/herself and tell the group his/her reason for visiting. As an introvert I admit I dread such moments, but I mentioned volunteering at the MAPS banding station at Rollins this summer. While the Sand Bluff volunteers were out on the third and final net-run of the night, Arthur and I remained behind and spoke with Lee about the MAPS work at Rollins and he told us quite a few fun banding anecdotes as we waited. It was really a treat to hear stories from someone with so much experience as a birder and bird bander.
After the third bird of the evening was banded, the few of us that remained were able to hold the bird, if we wished.
Squee!
The Sand Bluff Bird Observatory will have another Owl Night this Saturday, October 23rd. I highly recommend it!
I took more photos during the evening besides the ones shared in this post; you can find them here: Amy’s Saw-whet Owl banding photos.
During our recent visit to Holland, I had a free afternoon on my own in Leiden. I visited one of my favorite museums in the world, Naturalis, the national natural history museum of the Netherlands. The museum is always a treat to visit, but I really lucked out because one of the special temporary exhibits was an excellent study of bird migration.
The exhibit, Opvetten en wegwezen (Fatten up and go!), was presented in one large exhibit room. There were cases of mounted birds arranged by average migration distance. Information provided by each case showed the route each of the birds takes during migration.

Between these cases were various migration topics explained, like how birds navigate, the dangers birds face during their long travels, and how they prepare for the journey.

There were also several points where current bird research being conducted in the Netherlands was explained. A written interview with the involved scientists was shown, along with supplemental media. Here, the current work being done with Eurasian Spoonbills is explained by Ornithologist Tamar Lok. Small text (click to see full size at Flickr) reads, “The protection of birds in the Netherlands started with (Eurasian) Spoonbills. The Naardermeer was declared a nature reserve for this bird species. Later on, more marshes and coastal areas were declared protected.” I had no idea that the spoonbill was a ‘spark bird’ for Dutch bird conservation!

I was particularly interested in bird banding endeavors. A short video showed how Barn Swallow researchers work, and I was kind of wowed by the amount of birds caught in their nets.

The last bird cases were reserved for the birds with the longest migration routes. The final bird was the Arctic Tern, with a migration journey of 15,000 kilometers.
The Arctic Tern travels over 9,000 miles during migration!

Opvetten en wegwezen will continue at Naturalis through February 20th, 2011. I highly recommend it!
This morning Arthur and I are walking our Rescue & Recovery route to look for fallen injured or dead birds that have struck buildings in Chicago during the night and early morning. This is our fifth week volunteering for R&R this fall (we were off last week). During these weeks, I’d like to highlight some of the perils birds face on their migration by sharing a website or information about migratory birds.
This week has been rough on birds migrating through Chicago. The teams out earlier this week had large numbers of birds that hit windows in the city. Tuesday was particularly heavy, and a local news station picked up the story.
We prepared extra paper bags last night in anticipation of what may be another heavy wave of migration Wednesday night. We’ll be in the city by 4am Thursday morning.
Or, more accurately, falling behind. The weeks since our return from Holland have flown by — I can’t believe we’ve been back for over a month already! I’m behind on posts I’ve been thinking about for weeks, ugh! Hopefully I’ll be able to catch up soon. Meanwhile, the birds keep doing what they do, like these feeding fall plumage American Goldfinches I saw at Montrose Point Bird Sanctuary a couple of weeks ago.

I and the Bird is a long-running blog carnival that brings together posts from bird blogs every two weeks. Each edition is hosted by a different participant; this week the 135th IATB can be found at The Birder’s Report, a blog by Larry Jordan. This is the first time I have participated. Each host brings a different voice to the carnival, and I think Larry has done a wonderful job. Go check it out – read the latest in bird blogging while learning something about the bloggers themselves.
Mute Swans are a rather common sight here in the Chicago suburbs. They live on residential lakes, forest preserve wetlands, manicured corporate ponds. They are not native to the American Midwest, however, or even to North America.
Mute Swans are native to north central Eurasia, and we saw them all the time in the Netherlands, when we lived there.
A pair of Mute Swans we saw in the Netherlands in August
Mute Swans living outside of their native range here in North America are likely descended from ornamental escapees. Where breeding populations exist, the large birds may pose a threat to native waterfowl.
Mute Swans are large birds, weighing about 22 lbs as adults. As cygnets they are grey; plumage develops from into nearly overall full white once they reach adulthood. Adults have a bright orange bill, while juveniles have dark bills.
Like the population of native Mute Swans in Europe, some of the Mute Swans here in the United States migrate, while other populations remain year-round. Here in the lower Midwest, Mute Swans remain all year. The same is true for much of the European population, including the birds we saw in the Netherlands.
Mute Swans are not a federally protected species in the United States. Mute Swans were at one time protected federally under the Migratory Bird Treaty Act, but in 2005 they were officially declared non-native by the Department of the Interior.
I’ve had Mute Swans on my mind after speaking with different people about them earlier this week. I was surprised to hear some misconceptions about these large waterfowl, so I wanted to share a short post about them. If you want to learn more about Mute Swans, Cornell’s All About Birds is a wonderful resource.
