What Birds Fly at Night in California?

California, known for its diverse ecosystems and stunning wildlife, is home to a wide variety of bird species. While many birds are active during the day, there are also several species that take to the skies at night. These nocturnal birds have adapted unique features and behaviors to navigate and thrive in the darkness. In this article, we will explore some of the birds that fly at night in California and shed light on their fascinating nocturnal lifestyles.

1. Common Poorwill (Phalaenoptilus nuttallii):
The Common Poorwill is a small, stocky bird that is often mistaken for a type of owl due to its nocturnal habits. It is native to the western United States, including California. With a cryptic brown and gray plumage, the Common Poorwill is well-camouflaged during the day and becomes active at dusk, feeding on insects such as moths and beetles. It is known for its unique ability to enter a state of torpor, reducing its metabolic rate and conserving energy during periods of inactivity.

2. Western Screech-Owl (Megascops kennicottii):
The Western Screech-Owl is a small owl species found throughout California, inhabiting various habitats including woodlands, forests, and even urban areas. These owls have excellent night vision and rely on their acute hearing to locate prey such as rodents, small birds, and insects. Their distinctive calls, including a series of soft hoots and trills, can be heard echoing through the night.

3. Barn Owl (Tyto alba):
The Barn Owl is one of the most widespread owl species in the world, including California. With its heart-shaped face and pale plumage, it is easily recognizable. Barn Owls are efficient nocturnal hunters, using their exceptional hearing to locate small mammals like mice and voles. They can fly silently, thanks to specialized feathers that reduce noise during flight.

The Common Nighthawk is a medium-sized bird known for its unique aerial acrobatics. It has long, pointed wings and a streamlined body that allows it to maneuver swiftly in the air. Common Nighthawks are crepuscular, meaning they are most active during dawn and dusk. They feed on flying insects and are often spotted in open areas such as grasslands and deserts.


Q: Why do some birds fly at night?
A: Nocturnal birds have evolved to fly at night to avoid competition with diurnal (daytime) birds for resources such as food and nesting sites. Flying at night also reduces the risk of predation from diurnal predators.

Q: How do nocturnal birds navigate in the dark?
A: Nocturnal birds use various methods to navigate in the dark. Many rely on their exceptional hearing to locate prey and navigate their surroundings. Some birds, like owls, have specialized feathers that allow for silent flight, enhancing their ability to surprise prey in the dark.

Q: Can nocturnal birds see in complete darkness?
A: While they cannot see in complete darkness, nocturnal birds have adapted to low-light conditions. They have large eyes with a high number of light-sensitive cells called rods, which allow them to see in dim light. Additionally, their eyes are well-adapted to the dark due to a reflective layer behind the retina called the tapetum lucidum, which enhances night vision.
