Hummingbird banding blog by:

When I was looking for a place to stay in the Madera Canyon area, the Chuparosa Inn’s website showed that the Hummingbird Monitoring Network was scheduled to band hummingbirds on their property for September 19th. As a bander, I knew this would be THE place to stay in the Madera Canyon area. The prospect of being able to see hummingbirds banded and maybe being able to hold one was enchanting. The Hummingbird Monitoring Network (HMN) visits the Chuparosa Inn every 2 weeks from May to October to band hummingbirds. As Les previously wrote, the hummingbird feeders were busy during our stay, and the owners Luis and Nancy are nature lovers. So it was easy to see why the Chuparosa Inn was chosen by HMN as their banding site in the Madera Canyon.
HMN is a science-based, project-driven, non-profit organization dedicated to the conservation of hummingbird diversity and abundance throughout the Americas.
They support efforts to preserve habitats for hummingbirds, conduct/support research to gather more information about hummingbirds and promote their conservation, maintain long-term monitoring sites, and provide education by sharing information. For those of you who may know Devin Manky, he has been involved as Master Bander for hummingbirds with HMN. He works as the Wildlife Manager on Grouse Mountain and has banded many hummingbirds up on the mountain top. To learn more about this organization, please visit their website at:

Elissa Fazio arrived with a group of volunteers before dawn. She has been involved with the HMN since 2006, starting as a trapper and a data recorder. After a couple of years, she began banding in 2008. She is currently the Site Manager for Madera Canyon, Sabino Canyon, and Mt. Lemmon in Southeast Arizona. Being a Site Manager takes a LOT of dedication. She spends countless hours making the bands and compiling the data for HMN.
After their pre-dawn arrival, the morning began with the flurry of setting up the traps, shown below, around two hummingbird feeders, one nearby on the secondary patio, and the other in the forested area above the Inn. Then at 6:00am, they started the clock and banded hummingbirds for the next 5 hours.

Les decided to sleep in a little. By the time I was up and outside with my breakfast about 6:25am, they were banding and recording data for the third hummingbird of the day, a male MAGNIFICENT HUMMINGBIRD.
Elissa had charts to follow for each hummingbird species. These charts include information and pictures to help determine the age and sex of the bird.

Each bird arrived to the banding table in a mesh bag.

With each bird, she explained what she was examining. She started by banding the bird prior to removing it from the mesh bag. She delicately pulled the right leg through the mesh, wrapping the hummingbird in the mesh to protect it while she placed the band on its right leg. After placing the band, it’s important to review the band to ensure the band is properly closed so that there is no danger to the hummingbird.

Checking the band
After removing the hummingbird, she demonstrated the bander’s grip modified for hummingbirds, showing the brilliant colours on the throat feathers.

She continued examining the birds for various data, including bill measurement, wing chord, fat content, feather molt and the percentage of iridescent feathers. All of this information is utilized in determining the hummingbirds age. HY is for hatch year, which means a bird that was born this year, while AHY is for after hatch year, which is for all adult birds after the year they were born.
While measuring the bill, she also looked for corrugations in the bill.

She explained that checking the furculum for fat content provides information about how well the hummingbirds are storing fat for their migration.

While measuring the wing chord, Elissa described how the BLACK-CHINNED HUMMINGBIRD and the RUBY-THROATED HUMMINGBIRD (an eastern N.A. species) have unequal length width the primaries while ANNA’S and COSTA’S HUMMINGBIRDS (both Western N.A. species) have equal primary width

Female hatch year MAGNIFICENT HUMMINGBIRD had less white in the tips of the retricies, aka the tail feathers.

Reviewing the feathers
As male hummingbirds mature during their hatch year, the crown and/or throat feathers molt into the iridescent feathers. The percentage of iridescent feathers for both were taken.

Weighing the hummingbird was the last data collected. The hummingbirds were wrapped in tiny a “straight jacket” and placed on the scale.

After all of this, the hummingbirds were offered some sugar water before being released. Most of them weren’t interested in drinking, but this Black-chinned Hummingbird was only too happy to accept the reward.

Then…it was release time! The ANNA’S and BLACK-CHINNED HUMMINGBIRDS flew off immediately upon being placed on someone’s hand whereas the MAGNIFICENT HUMMINGBIRDS were much slower to depart, sometimes taking up to 5 minutes. I was in awe of holding a tiny male for a few minutes before Elissa placed him on another person’s hand. He did, however, leave a liquid present behind!

At 11:00 am, hummingbird banding finished with a total of 17 hummingbirds – 3 ANNA’S, 4 BLACK-CHINNED, and 11 MAGNIFICENT. This was a “magnificent” experience overall! Everyone enjoyed the banding very much. Thank you so much to Elissa and your volunteers. I learned a lot! It was a great pleasure meeting you all. I really admired your hospitality to us and the other individuals who came to observe your banding station and learn about hummingbirds. Also, a big thank you to Luis and Nancy for allowing HMN to use your Inn as the monitoring site for Madera Canyon. We’ll be back!!
