The third MAPS banding session at Rollins Savanna this season took place on Sunday, June 20th. Yet again skies threatened rain during the morning, and yet again we were lucky with no drops falling during the time the nets were up.

This time, the nets were slow as the day began. The second half of the morning was very busy and there were almost constant net-runs while some of us remained at the table to process the large amount of birds that were coming in.

I did a lot of paperwork and often left the banding to others. I banded just seven birds in total. When I visited the team last year I was amazed that some people were handling and examining the bird and also doing the paperwork themselves. During the busy moments of the morning, I learned that writing down your own data really isn’t too tough. For two of the birds I banded, a juvenile Orchard Oriole and a Song Sparrow, I also took the data down myself. Additionally I banded two Baltimore Orioles, a Cedar Waxwing, an Eastern Wood-Pewee and a juvenile Eastern Bluebird.

We had a lot of Cedar Waxwings in the nets. Here’s one that someone else banded. Check out those wax tips in the second photo.

We had a few more juvenile birds too, including this baby Northern Cardinal.

One of the coolest birds we had was a female Brown-headed Cowbird who was obviously gravid – with egg! She was processed very quickly and sent on her way to do her deed!

The second MAPS banding session at Rollins Savanna this season took place on Friday, June 11. Again we lucked out with the weather; rain was threatening for most of the morning but nothing came down until after the nets were put away.

This session was a bit more relaxed than the first time, with a higher ratio of banders to birds. I banded five birds: COYE [Common Yellowthroat]; AMRO [American Robin]; BRTH [Brown Thrasher]; TRES [Tree Swallow]; and SOSP [Song Sparrow]. Again Janice Sweet was taking photographs of the day’s activities, and I was delighted to find she had captured shots four of the five birds I banded!

We band the birds on their right legs. Here you can see I am holding the bird and controlling the right leg as the pliers approach the leg with the band.

Here’s an image of me transferring the Tree Swallow from the photographer’s hold to the bander’s hold. See my right index and middle fingers are spread apart, ready to hold the bird’s head and neck gently but firmly.

By the way, you might notice I’m wearing the same shirt as last week – I Put Out For Birds. It got stained (ruined) the first week, so it’s now my banding shirt forevermore.

We had the first juveniles caught for the season: a WBNU [White-breasted Nuthatch] and a DOWO [Downy Woodpecker]. The DOWO was extremely cute, as you can see:

Since it wasn’t too busy for most of the day, we had more time for photos. I managed to post a picture of the baby Downy Woodpecker to Facebook while in the field.

Late in the morning we were treated to a visit by a Great Spangled Fritillary, who posed on all sorts of objects on our banding table.

Finally, a Blue Jay provided comic relief when it held tightly onto some prized seeds while it was being processed. Those tasty seeds may have saved the bander from a bite or two.

Many thanks again to Janice Sweet for the use of her photos. The third session took place on June 20th — with highlights coming soon!

Shortly after we set up for the second banding session at Rollins Savanna last week, I was handed a CD full of photos from the first week. Janice Sweet took photos of the banding team all morning, and I requested permission to share some of them here on the blog. All of the following photos are from the May 31st session.

The first thing we do when processing a bird is to determine the species. For most birds this is not a problem. Although not all of the bird banders in our group are also birders, there are enough team members that can quickly and confidently identify the birds. When we catch an Empidonax flycatcher, ID can get a bit tricky.

After the bird is identified, a band is placed around the leg. The band sizes for each species are listed in the Pyle guide. For example, a band size of 2 or 3 is mentioned for the Blue Jay. Here the bands are being held up by the bird’s leg to determine the appropriate size for this individual.

Next the band is carefully pulled apart using a special pair of pliers. The band is then transferred to the appropriately-sized hole in another special type of pliers to be placed onto the bird. Here are some photos of bands being applied.

Next we determine the sex and age of the bird. For sexually dichromatic species, like Northern Cardinals, Baltimore Orioles or American Goldfinches, determining sex is easy.

For other species, we look for things like a brood patch or a cloacal protuberance to determine sex. To view these, we blow gently on the bird’s abdominal area to clear away feathers. You can see that the feathers of this Brown Thrasher are being blown up away from the body.

Without getting too technical, age is often determined by looking very closely at certain feathers. We also look at the level of bone growth in the skull, viewed by clearing away head feathers with a bit of water. Eye color, other plumage clues and even bill color are also used to help determine age.

Next, more measurements may be taken, including wing length, feather wear, feather molt, and fat level.

Throughout the entire process, the safety of the bird is foremost in our minds. Part of this is keeping a firm but gentle grip on the bird during the procedure, and processing the bird quickly for a timely release.

My heartfelt thanks to Janice Sweet for allowing the use of her photos. Thanks, too, to the rest of the team. I am learning so much and having a lot of fun! Our second session was on June 11, and our third is planned for June 20. I will have more to share about these soon!
