🎶 Listen to the Bermuda Longtail! 🐦🔊 This video, shared by one of our citizen scientists, captures their unique calls. Have you heard a Longtail before? Surprised by their sound? Let us know! #BermudaLongtail #BirdSounds #CitizenScience #BioQuest

Do you know about the success of Bermuda’s Cahow Recovery Programme? We highly recommend familiarizing yourself with this #biodiversity #conservation success story (and following BermudaCahowCam) for some much needed inspiration & hope! #AllWeCanSave thebermudian.com/home-a-garden/…

🌍✈️ Did You Know? Our Bermuda Petrel, affectionately called the Cahow, can fly more than 250,000 miles in its lifetime. That’s the equivalent of circling the globe ten times! 🌊🐦

Until recently, no Cahow nested on Nonsuch or other larger Bermuda islands since the 1620s, when Cahow numbers dwindled because of the human settlers and the introduction of mammal predators. Thanks to the Translocation Project, chicks started hatching on Nonsuch again in 2009:

Initiated and run by Dr. David Wingate from 1962 to 2000, the Cahow Recovery Program has been led by Mr. Madeiros since 2000, also in collaboration with researchers from Bermuda, the U.S., Canada, Italy, Australia... It's part of a larger ongoing project—the Rewilding of Nonsuch.

There were only 18 pairs at the start of the recovery program, going up to 160+ pairs today. That sparked concerns about inbreeding. As the research from BioQuest by CariGenetics shows, luckily that doesn't seem to be the case. The CahowCam1 female is also part of the study:

6/2 14:46 During her last health check, the CahowCam1 female weighed 360 g, which is still a solid number for females. For comparison, she weighed nearly 400 g in January. She's one of the biggest females in the colony.

Again, for more details about the CahowCam1 female's health check, about how Vega (the CahowCam1 chick) fledged on 5/28, and also for more news about the current state of the Cahow colonies, check out this entry and watch the embedded video: nonsuchisland.com/blog/record-br…

BermudaCahowCam Scilly Pelagics I was lucky enough to be in Bermuda last November to see the Cahows pairing up and returning to their burrows. A guided tour of the burrows on Nonsuch by Jeremy who knows all the birds by family history was a highlight. Would really recommend it. Great fall Yank migration too.

Do you wonder where breeding Cahows go each time they leave their nests? This map shows the trips of the CahowCam1 male during the 2009-2010 breeding season (between November and June). As wide-ranging seabirds, Cahows traverse great distances.

While it's up to each bird to find the best foraging spots, most Cahows share a similar general pattern, spending the summer ~2200 mi. (~3500 km) to the northeast of Bermuda, almost on the other side of the Atlantic Ocean. Some go up to 60° north, close to Iceland and Greenland.

Each Cahow is fitted with an identification band made from a special corrosion-resistant alloy. The band stays on the bird's leg safely for the entire duration of the Cahow lifespan, so up to 50 years. The CahowCam1 female's ID band still looks brand new after 18 years:

The CahowCam1 pair has been nesting on Nonsuch Island together since 2010. The female (left) and her mate (right) were both translocated as chicks from the small nesting isles in 2006. During translocation, each was fed by Jeremy for a few weeks before fledging to sea.

In collaboration with Nonsuch Expeditions, the Department of Environment and Natural Resources (DENR) recently announced the successful conclusion of the 2024 nesting season for the Bermuda Petrel. With 76 fledged chicks, including a record 25 on Nonsuch Island, the dedicated
