Bats can Focus Biosonar by Stretching Mouths

While in Cockpit Country for our first expedition to Jamaica looking for the Golden Swallow, John, Justin and I watched in awe as hundreds and hundreds of bats flowed out of a cave and flew in a distinct path right by us over the course of half an hour. The slightly shoddy video below can only partly convey the sensation of having the flapping mammals zoom past in a steady stream. We’ve recently featured a couple stories of scientific developments in bat research on the blog, including wing-beat echolocation in fruit bats and singing for communication in other species.

A couple weeks ago, we learned via Discover Magazine’s science blog by Continue reading

It’s been a while since you last heard from us, but not because we’re lost in the Jamaican wilderness!

We arrived back in Ithaca, NY a week ago, and have been hard at work processing our data, photos, videos, and thoughts from this past trip to the Blue Mountains. In addition, we’ve had to analyze our data from both trips combined, trying to seek out patterns in aerial insectivore sightings and making maps of all our point counts with different species seen in both Cockpit Country and the mountainous eastern portion of the island.

We’re also looking up references to all information on Cave Swallows, Antillean Palm Swifts, and White-collared Swifts in either Jamaica, the Caribbean, or the world, depending on what kind of journal articles have been published about them in the past. Other research we’ve been doing involves Barn Owls and Turkey Vultures, which will be the subject of spin-off Continue reading
