To Catch a Predator

Want to be a raptor bander? You'll need live bait, a taco trap, a good hand cream, and years of licensed training.

On a windy day in Hilton, New York, four聽bird banders from Braddock Bay Raptor Research聽(BBRR)聽sit in a wooden blind聽about twice the size of a聽garden shed, their binoculars poking through slits in the wall. They search the skies for raptors鈥攁nd though it's not the best weather, they鈥檙e in luck. A Sharp-shinned Hawk聽rides the gale into their sightline.

Bingo.

Now comes the tricky part:聽getting聽the bird of prey聽down to the ground.聽Unlike with songbird banding, where birds fly straight聽into nets stationed in the woods, raptors need to be coerced into deviating from their path. There聽needs to be a diversion鈥攁nd it needs to be live.

The Migratory Bird Treaty Act doesn't protect聽Rock Pigeons, European Starlings, and聽House Sparrows because they鈥檙e non-native,聽invasive species; so, at BBRR, starlings and pigeons become bait.聽They鈥檙e outfitted with tiny leather vests and tethered to a聽fishing line that trails into the blind. When a raptor is spotted, the bander will pull on the string, lifting the little soldier bird up and down in the air so that it looks injured. Easy prey . . .聽or so it would seem.聽

鈥淗ere comes the sharpie,鈥 says one of the banders.聽Another pulls on the聽tethers like a master聽puppeteer, causing a聽starling and pigeon to cartwheel up and聽down in the open field.聽Like an arrow, the hawk dives towards the starling.

Bam!

A spring-loaded net shaped like a taco shell snaps over the hawk. The聽starling, a little flustered, stands up, ruffles its wings,聽and sidesteps its captive predator.

Barb French opens the blind door聽and walks out聽into the field. She bends down and checks on the starling. (It's fine.) She detangles the lines, then聽opens the trap, grabbing the sharpie by the feet.

She looks down at her favorite raptor and smiles.聽For someone who owns a referral聽business for pedigreed-cat breeders, French admits she's a strange fit for the world of bird banding.聽After recovering from a broken foot, French鈥檚 doctor told her she needed to start exercising again. Not a fan of the gym, she聽started taking long walks outside鈥攁nd eventually, began birding. Raptors,聽especially Sharp-shinned Hawks,聽mesmerized her.

After taking a few birding classes, French聽discovered that anyone鈥攏ot just聽辞谤苍颈迟丑辞濒辞驳颈蝉迟蝉鈥could train to be a licensed bird bander. She spent three years working toward her聽license, which allows her to capture certain species聽and gather the necessary data on them.聽She now聽works as a sub-permitee on BBRR's seven-person raptor team,聽under long-time master bander聽Dan Niven.

One of the blinds French covers聽is based on the shores of Lake Ontario, which is a popular flyway during migration season. The more than 7,000 square miles of water act聽as a wall, pushing birds straight into the station鈥檚 path.聽

BBRR聽welcomes human visitors as well; it claims to be the only raptor-banding center聽in North America open to the public without appointment.聽Today, a clump of people have gathered to watch聽the sharpie鈥檚 capture. It all happens in about five seconds鈥攂etween the starling leaping, the hawk swooping down, and the bander releasing聽the trap.

The role of the lure birds doesn鈥檛 always sit well with visitors, but French explains that with the protective vests and the banders on the sidelines,聽they're more or less聽safe and sound.聽鈥淲e don鈥檛 want the hawks to injure or kill [them],鈥 French says. 鈥淢any people have tried to come up with some sort of a fake lure鈥攔obotic birds, birds that have been made carefully with feathers. Hawks just don鈥檛 fall for them.鈥澛

As soon as the raptor begins its descent, the bander pulls another tether to release a spring-loaded bow trap. The metal, mesh-covered oval is so powerful and quick, it traps the raptor before it reaches the bait. If the bird isn't directly in the middle of the net, however, it could get injured. It takes years of training to master this maneuver, French says鈥攐nly the聽experts are allowed to try it on a real bird.

As French goes out to retrieve the catch, she leaves her gloves behind.聽鈥淭o protect us from, say, a determined Red-tail, the gloves would have to be so thick that we couldn鈥檛 move our hands,鈥 French says. 鈥淲e have to be able to feel what we鈥檙e doing, because with some of the really small birds, if you squeezed them too hard, you could easily break their legs.鈥澛燘ites and scratches are a steady part of the job. As a precaution, French and other banders are recommended to get tetanus shots every five years, rather than聽10.

Back inside the blind, there鈥檚 a plethora of empty cans. French's聽sharpie goes head first into a Pringles container. On the floor is a trash can鈥攋ust in case a Bald Eagle makes an appearance.聽The team typically gets聽Sharp-shinned, 搁别诲-迟补颈濒别诲,听and Cooper鈥檚 Hawks, with a sprinkling of聽American Kestrels, Merlins, Rough-legged Hawks, Red-shouldered Hawks, Northern Goshawks, and the occasional Bald Eagle (usually a juvenile).聽

The darkness inside the can tends to calm the bird down, while providing easy and safe access to its feet.聽Niven slips on a numbered aluminum band to one of the legs, then weighs its body聽and measures its wing chord.聽French writes down the measurements, which get聽sent to the U.S. Geological Survey鈥檚 . Researchers use that data to track migration patterns, species鈥 population numbers, and other vital trends among raptors.

BBRR聽typically bands between 200 and 500 birds a season;聽but over the years, French says it's聽seen a decline in the number of smaller species, such as聽kestrels聽and Merlins, passing through. It鈥檚 unclear what鈥檚 causing the decline, though some researchers speculate it could be from聽increased predation by other birds of prey, death by pesticides, or competition with invasive species such as the starlings. The center is keeping track of this聽potentially worrying pattern.

Finally, after the hawk聽is measured and braceleted, French will allow visitors to snap a few pictures鈥if the bird isn鈥檛 too stressed. 鈥淭hen comes the part the raptors like聽the best,鈥 French says.聽鈥淲e let them go.鈥

And what becomes of the聽lure birds? Once migration is over, they're free to fly away. It's likely they'll聽cross聽paths with a raptor again鈥攖hough this time聽under聽slightly聽different circumstances.

Correction: Braddock Bay is the only raptor-banding station open readily to the public; there may be songbird-banding stations that are just as accessible around North America.
