This is one of 11 box turtles that were saved from the Costco development in NE DC. Here you can see the tiny radio transmitter that’s epoxyed onto the turtle’s carapace. DDOE Fisheries & Wildlife had been tracking these titles for four years. #terrapenecarolina #boxturtle #thisisDC #igdc #dcnature (at United States National Arboretum)

The blue in jay feathers (and all other blue bird species) is structural/spectral, not pigment-based. The result is incredible color saturation in the right light. #igdc #dcnature #thisisDC #feathers #bluejay #latergram
