BROWN-HEADED NUTHATCH
SCIENTIFIC NAME: Sitta pusilla
POPULATION: 1.4 million
TREND: Decreasing
HABITAT: Loblolly, Longleaf, Shortleaf, and pine-oak forests.
The perky, social Brown-headed Nuthatch never strays far from its favorite pine-forest habitat, where small flocks range through the trees, easily detected by their squeaky calls. Even smaller than its close relative the White-breasted Nuthatch, it’s no wonder that this tiny songbird’s species name is pusilla, Latin for “very small.”
Tiny Tool-User
The Brown-headed Nuthatch, like the Green Heron, is one of the few birds in the world known to regularly use tools. When foraging, it may select a flake of pine bark, then use it as a lever to pry up bark scales to get at food hidden beneath, usually insects and spiders or their eggs. This enterprising little bird has also been observed using twigs and pine needles as tools. A Brown-headed Nuthatch will even carry its tool from tree to tree as it forages, or use it to cover up a cache of seeds.

BIRD OF THE WEEK — SOUTHERN SCREAMER — PLANET EARTH BIRD WORLD group

PLANET EARTH BIRD WORLD has over 1,600 members and over 130,000 photos and videos.
BIRD OF THE WEEK
SOUTHERN SCREAMER
SCIENTIFIC NAME: Chauna torquata
POPULATION: 100,000–1,000,000 individuals.
TREND: Stable
HABITAT: Freshwater tropical and sub-tropical wetlands, including lakes, marshes, flooded grasslands and lagoons.
The Southern Screamer (also known as the Crested Screamer) may look ungainly at first glance, with its big body, disproportionately small head, and thick legs. But this large, gray marsh bird, closely related to geese and other waterfowl, is actually a strong swimmer and flier.
Screamers are the “guard birds” of their habitats; their trumpet-like calls can carry for several miles, warning other birds, such as Blue-throated Macaw, Orinoco Goose, and Streamer-tailed Tyrant, of approaching danger.

SIERRA CLUB — A NEW THREAT TO HARP SEALS — PLANET EARTH IN SEPIA group

The Canadian government has banned commercial hunting of these vulnerable white pups since 1987 and established strict rules for tourist interaction. That helped to protect the population, but climate change brings new uncertainty to their future. Already the Magdalen archipelago is experiencing stronger storms like Hurricane Dorian, which tore away parts of the islands in 2019. And a diminishing ice barrier no longer protects against winter storms. One study shows that temperatures around the islands have “warmed 4.2 degrees Fahrenheit since the late 19th century, twice the global average.”
The difficulty in reaching harp seals is not for lack of seal numbers. According to Canada’s Department of Fisheries and Oceans (DFO), they are 7.4 million strong in three population groups (Northwest Atlantic, Greenland Sea, and White Sea/Barents Sea). The problem is retreating ice resulting from warming waters. This ice loss affects both the seals, who pup on the ice to avoid predators, and the humans on Quebec’s Magdalen Islands, who rely on the ice for protection from winter storms.
