Field Frame Friday: Drool-cicle Dreams.

Not all behavioral observations go into datasheets and end up in academic journals. Antarctic seals, like this Weddell seal (Leptonychotes weddellii)drool while sleeping, but its so cold (summer temperatures as low as −26 °C or −14.8 °F) that it freezes into a drool-cicle!

Field Frame Friday: Perks of studying in your “own backyard”.

For some researchers, the field is considered to be far-off places around the world. For others the field is our local environment, such as the Marin Headlands just across the Golden Gate Bridge in Sausalito, California. It is always a bonus when the notorious coastal fog burns off and reveals stunning natural views. [Photo and…

Field Frame Friday: Lunch is served

Deep breath in!

Unlike human nostrils which remain open at all times, the relaxed nostril position for pinnipeds is in a closed position. Like this harbor seal (Phoca vitulina) they voluntarily open them when at the surface of the water to sniff or breathe.

Field Frame Friday: Hygienic bees

This photo shows a circular section of comb that bees have (mostly) cleared of larvae that were made to simulate diseased brood. Bees will remove the capping on these “diseased” larvae and take them out of the hive before the pathogen can reach it’s infectious stage, thus keeping the colony healthy! We usually hope for…
