Break from the tropics
Yes, you guessed it, this is not a photo from the recent Costa Rica trip. I thought a frosty retreat from the steamy tropics was in order, and decided to insert this flashback of a favorite photo and sighting from 
a 2004 trip to the Antarctica Peninsula: a Gentoo penguin parent about to feed its chick. This is the bill-tapping action that encourages each bird to open wide to complete the transfer of semi-digested krill from the adult to the chick.
Enjoy!
(I didn’t have a weblog back then, so periodically I post flashbacks from this trip and a later Galápagos adventure, which were both fabulous voyages with family.)
