One of the populations of killer whales that spends part of the year around the San Juan Islands north of Seattle is called the Southern Resident killer whales, and theyâre very endangered. There are only 81 of them left in the wild. Thatâs the bad news. But the good news is that 81 is five more than there were last year. There was a baby boom among the Southern Residents recently, and for a population of this size, five new individuals is a very big deal.
In this video podcast weâll look at several amazing photographs that give us a glimpse not only of some of the new calves, but also of the family lives of these social animals. The photos were taken with an unmanned aerial vehicle, and to help us understand the photos we have one of the scientists who took them On the Line with us today.
John Durban is a marine mammal biologist with NOAA Fisheries, and he recently got back from the research expeditionâa collaboration between NOAA Fisheries and the Vancouver Aquariumâthat yielded these incredible pictures. Durban explains that these photos, in addition to being beautiful, are also full of data that help scientists monitor the health and reproductive success of this very endangered group of whales.

Note: The researchers kept the UAV at least 90 feet above the whales at all times to avoid disturbing them. In addition, they were operating under research permits from NOAA Fisheries and flight authorization from the Federal Aviation Administration when in U.S. waters, and from Fisheries and Oceans Canada with flight authorization from Transport Canada when in Canadian waters.
