Ken Bailey spotted this mother/calf pair headed north. The calf here is on the right side of its mother, staying close for protection. Killer whales prey on Gray Whale calves.
NOAA, National Oceanic and Atmospheric Administration, has a hexacopter drone, which can safely photograph marine mammals from above. Here is a recent photo shared on Journey North of a Gray Whale mother with her calf. The photo is courtesy of Wayne Perryman.
Thanks to Ken for allowing me to share his photo. To see much more of Ken's nature photography, including underwater photography, here is his website: http://www.seadreams.org/
