Hummingbird by John S

Hummingbirds are birds native to the Americas and constituting the biological family Trochilidae. They are the smallest of birds, most species measuring 7.5–13 cm (3–5 in) in length. The smallest extant bird species is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz). They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species, to in excess of 80 in some of the smallest. Of those species that have been measured in wind tunnels, their top speeds exceed 15 m/s (54 km/h; 34 mph) and some species can dive at speeds in excess of 22 m/s (79 km/h; 49 mph). Hummingbirds have the highest mass-specific metabolic rate of any homeothermic animal. To conserve energy when food is scarce, and nightly when not foraging, they can go into torpor, a state similar to hibernation, slowing their metabolic rate to 1/15th of its normal rate.

Reticulated Glass by Afzal Karim

This Reticulated Glass Frog was captured in Costa Rica. This is basically a non-venomous tree Frog. It’s very tiny and shines like a glass. This is probably why it’s called a Glass Frog. This was taken using a macro lens which is why the details of the frog are very prominent.
