The Henslow’s sparrow has the simplest and shortest song of any North American songbird, a thin tze-lick insect-like song, accurately described as a “feeble hiccup.”

Male Northern Bobwhite

Northern Bobwhite

Northern bobwhites have a high annual mortality rate and short life spans. When weather and habitat conditions permit, however, they can compensate for this high mortality with increased chick production. An adult pair can successfully produce two or more broods (≥25 offspring) during a single breeding season.

Chestnut-collared longspur (male)

Chestnut-collared Longspur

These birds derive their name from their coloring and the elongated claw of the backward-facing toe, the “longspur”. Unlike many songbirds that live in forests, chestnut-collared longspurs and other grassland birds do not hop on the ground, but walk or run.

A New Mexico jumping mouse

New Mexico Meadow Jumping Mouse

Beavers significantly impact New Mexico jumping mouse habitat as their dams create slow moving, permanent water sources that encourage diverse and dense vegetation growth that the mice rely on. Beaver activity can also act as a natural fire break.

A western jumping mouse

Western Jumping Mouse

When western jumping mice emerge from hibernation in late spring or early summer, they have lost 18% of their body weight from the previous year. Adults quickly build up their fat reserves of up to 2/3 of their body weight to survive the long winter underground without food stores.

A chiricahua leopard frog among grass and riparian vegetation.
