For the last six months, Naples resident Colleen Gill has been patrolling Southwest Florida beaches looking for animals in distress and sharing her findings on social media.

“Giving people in real time what's happening to our beaches and showing them the decline that’s happening and bringing them into reality a little,” Gill said.

Gill said she is motivated by a personal mission to shed light on the impacts the deteriorating water quality is having on marine life.

She is on a residential stretch of beach on Marco Island, where more than 100 birds have been found dead or dying over the course of the last three weeks.

Gill and Joanna Metzger have been collecting sick birds on a residential stretch of beach on #Marcoisland and rushing them to the @ConservancySWFL's #Vonarxwildlifehospital for the last three weeks, where as of Friday only 8% of the birds that make the car trip survive. @wgcu pic.twitter.com/G4m5L8hb1Z — Andrea Perdomo (@am_perdomo) December 5, 2018

Most of the birds being affected are small migratory common and sandwich terns.

“There’s been really extreme situations where they’re convulsing and dropping dead, like, right in front of you," Gill said. "It’s not a slow, delayed process. So, a lot of the birds that we are scooping up, they aren’t even making it to the wildlife hospital alive.”

Moments after a small flock of birds takes flight, one falls out of the sky and into the water.

Gill takes off running mid-sentence to rescue the bird.

"Sorry, I didn't want it to drown," Gill said between breaths after emerging from the Gulf. "You see? Dropping out of the sky. Literally dropping out of the sky.”

Increasing Numbers

Gill meets up with Joanna Metzger, who pulls a blue wagon behind her. In it are sick birds she gently places in towel-lined shoeboxes.

Metzger showed Gill the sick birds she collected so far that morning.

“This one can still move a little bit, but he is definitely feeling the effects," Metzger said. "This one didn’t make it." She paused. "Gosh.”

Metzger said she visits the beach every day, and at the beginning of November, she encountered a couple dead birds while on a bike ride.

“I started bringing my car with a wagon, so I can have more room because, the next day, there were six deceased," Metzger said. "The next day after that, there were eight. The next day, there were nine dead."

No Known Cause

Volunteers like Metzger and Gill rush the sick birds to the nearby Von Arx Wildlife Hospital in Naples, where only eight percent of the birds that make the car ride survive.

Hospital Director Joanna Fitzgerald said she’s never seen anything like it.

“The hard part is most of them are dying within an hour or so," Fitzgerald said. "We’re not even getting into a real solid treatment plan that we know will work because they’re passing away faster than we can help them, honestly.”

Fitzgerald said samples were sent to the state to determine what is killing the birds the day before Thanksgiving — but hasn't heard back — so there is no official cause yet.

In the hospital parking lot, Metzger discussed the fate of the patients she brought in that day.

“Three died on the way. The one that fell out of the sky is a laughing gull, and the other is a common tern," Metzger said. "So, those are the two that are alive. I had five that are deceased. You know, it’s just never ending, so I just don’t know when it is going to end. When everything’s dead? Are we next?”

Back at the beach, Gill walks among the remains of birds that didn’t survive long enough for an attempted rescue.

Beach rakers rolled over the carcasses of those birds, and now, parts of the deceased birds are strewn across the white sand.

"This is great for tourism,” Gill said.

She glances at a small flock of terns out near the edge of the water — which Gill said is about a third of its normal size — and, then, continues walking in search of birds that need saving.
