March 17, 2020 - Rufous Fantail (Rhipidura rufifrons)

The fifteen recognized subspecies of these fantails are found in eastern Australia and parts of Indonesia, Micronesia, the Northern Mariana Islands, Papua New Guinea, the Solomon Islands, and Timor-Leste. Often foraging in mixed-species flocks, they eat a variety of insects and spiders, capturing them in short flights or picking them from plants. Pairs build compact cup-shaped nests from grass and fine plant fibers held together with spiderwebs, usually in forked branches. Both parents incubate the eggs and feed the chicks.

April 1, 2020 - Eastern Pondhawk or Common Pondhawk (Erythemis simplicicollis)

These skimmers are commonly found near ponds and other slow-moving bodies of water in central and eastern North America and parts of Mexico, the Caribbean, and Central America. They are aggressive predators, hunting insects, such as lacewings and large dragonflies on the wing. While young, they hunt away from the water, but after reaching breeding age they return to ponds, where males defend mating territories. Females lay their eggs on floating mats of algae while males fly nearby to defend them.

March 11, 2020 - White-rumped Sandpiper (Calidris fuscicollis)

Breeding in arctic Canada, these sandpipers migrate through the eastern United States, parts of Central America, the Caribbean, and much of South America to winter in southeastern South America. They eat mostly invertebrates, such as midges, flies, beetles, bloodworms, and marine worms, along with some seeds. During the breeding season males defend nesting territories. Females build nests in depressions on the ground from grasses, sedges, willow leaves, moss, and lichen. Once the females have laid their eggs, the males depart, leaving them to incubate the eggs and care for the chicks alone.

March 7, 2020 - Black-vented Shearwater (Puffinus opisthomelas)

Breeding on islands off the coast of northwestern Mexico, these shearwaters are found along the Pacific coast from central California to southern Mexico. They eat small fish, including anchovies and sardines, possibly along with some small squid and crustaceans. They capture their prey at or near the water’s surface while swimming, or in shallow dives from the surface or the air. Nesting colonially on islands, they dig burrows in the ground or nest in rock crevices. Both parents probably incubate the single egg and feed the chick, visiting the colonies at night. They are classified as Near Threatened due primarily to population declines in the past from habitat degradation and introduced predators.
