A male and female Mallard duck standing in grass near the base of a tree.

The Mallard (Anas platyrhynchos) has over 800,000 observations on iNaturalist, making it one of the most-documented birds on the platform. But every new observation still has the potential to reveal something we don't know ... yet.

"Common" doesn't mean unimportant! When you share your nature photos on iNaturalist, you're contributing to science & conservation ... plus, when you stop to look, you might learn something new about a species you thought you knew.

Also, ducks are great. Pls never stop sharing your duck photos. πŸ¦†πŸ’š

An airplant with long slender light green leaves and small yellow flowers grows on a rocky cliffside.

An airplant with long slender light green leaves and small yellow flowers grows on a rocky cliffside.

This endangered airplant's scientific name is Tillandsia crocata, and there are currently only 12 records of it on iNaturalist! Like other airplants, they don't need soil to get their water and nutrients ... meaning they can grow in spectacular places like this rocky outcropping.

Blue-green glowing larvae that look like strands of beads hang down from a cave ceiling.

Blue-green glowing larvae that look like strands of beads hang down from a cave ceiling.

Larvae can also detect each other's light and synchronize their glow with neighbors, turning a cave ceiling into one coordinated trap. Nature always finds a way ... and sometimes that way is very, very pretty.

Behold Arachnocampa luminosa, aka the New Zealand glowworm. The larval forms use their blue-green bioluminescence to lure prey into silk snares (meanwhile, the adults take the form of tiny gnats).
