Life cycle & population of the Polioptila melanura & Aves

Life cycle: Polioptila melanura reproduces by laying eggs in a nest. The nest is usually built in a tree or shrub and is made of grass, feathers, and other materials. The female will lay between 3 and 5 eggs, which will hatch after about two weeks. The young birds will stay in the nest for about two weeks before they are ready to leave. After leaving the nest, the young birds will stay with their parents for a few weeks before they are able to fly and find food on their own. The birds will reach sexual maturity at around one year of age.

Average offspring size: 10-14 cm

Most common health issues: Respiratory Infections, Gastrointestinal Infections, Parasitic Infections, Stress-Related Disorders, Nutritional Deficiencies, Reproductive Disorders

Threats: Habitat Loss, Disease, Pesticides, Predators (Cats, Hawks, Owls, Snakes)

Population: Polioptila melanura's population has been steadily decreasing since the early 2000s, with the lowest population count in 2018. The population peaked in 2002, with a count of over 1,000 individuals. In the last ten years, the population has decreased from over 800 individuals in 2009 to just over 500 individuals in 2018.

Black-tailed Gnatcatcher Environment

How do Black-tailed Gnatcatcher adapt to their environment Polioptila melanura, commonly known as the black-throated gray warbler, is a small migratory bird that is found in North America. It has adapted to its environment by having a long, pointed bill that is perfect for catching insects, which is its main source of food.
