Are house wrens good to have around? House wrens are extremely aggressive and territorial. They don’t like other birds nesting nearby within their small territory. What do wrens eat? Wrens like peanut pieces, mealworms, suet blends, and sunflower chips. They rarely abandon their babies. Wrens will attempt raising two broods a season at different nest sites. Despite small size, wrens sing loudly. Wrens were considered sacred birds. Their feathers were thought to be charms against disasters. How can you identify a wren? Carolina wrens have loud “tea-kettle” songs. Their nests are often in hanging plants. Rock wrens are pale brown with long tails.
Do House Wrens return to the same nest?
The house wren’s nest site fidelity is high. It might come back to the same nest if it’s still there. It will clean up the nest if it’s in reasonable shape. House wrens do usually return to the same general territory year after year.
Males and females have high nest site fidelity, returning to the same or nearby territory each year. Wrens eat mostly tiny insects. They hunt spiders and insects, such as beetles, bugs and various caterpillars.
If the previous nest is not removed, the wren will renovate it with a thin layer of nest material plus a new nest lining, often within a day or two after fledging. Maybe 1/4 to 1/3 of males may return to the same breeding territory each year.
When the babies are 12 to 14 days old, they leave the nest. The parents still feed them. Within 2 weeks, the pair has normally started building another nest.
Wrens will attempt raising two broods a season. Second broods are raised at a different nest site. Wrens have 2 broods per year, rarely 3.
House wrens are cavity nesters, nesting in old woodpecker holes or bird houses. Males build several nests to entice a mate. In Western New York they begin building their nests in the middle of May and lay eggs in early June.
Male and female Carolina wrens build their nests together. One member of the pair may stay at the site while the other gathers material. Male house wrens clean out the old nesting material between clutches.
Are House Wrens invasive?
Unlike the invasives, House Wrens are native. You may not legally remove nesting material, eggs, nestlings, or adult House Wrens. Wrens will take over others’ nests by destroying eggs.
Wren House Placement: Partial shade near the border or a large tree. Install 3 to 10 feet off the ground. Which direction? Away from winds, which for most is East, then North, South and West. Keep in mind, birds may choose North first.
Wrens prefer a secluded area with cover. Providing feathers, moss, twigs, and grass encourages nesting. Some species readily use 1-2 inch entrance holes. Males scout in early Spring. Song attracts a mate.
They have many predators including cats, rats, snakes and owls. They primarily eat insects like beetles, caterpillars, grasshoppers and moths.
The male first builds a stick base supporting the nest. This base is unique among cavity nesters, identifying it. The nest cup size stays consistent despite variations in cavity shapes and sizes. They use existing cavities or woodpecker holes since they cannot excavate.
Wrens are aggressive and attack other species nesting nearby. They compete for resources. Removing old nests may not impact re-occupancy.
Wrens like peanut pieces, mealworms, suet, sunflower chips. They sing to attract a mate and defend territory. Nests resemble a pile of twigs with a feather-lined cup. Eggs are white with reddish-brown spots. Material and structure differs from House Sparrows.
How long do House Wrens stay in the nest?
The house wren stays in the nest for 12 to 18 days after hatching. The new birds might not even be 2 weeks old when they take their first flight.
Wrens have two, sometimes three, broods each year. The incubation period for the eggs is 12 to 15 days. The female wren incubates them. Once hatched, both parents feed them until grown enough to leave the nest after 12 to 18 days.
Wrens are migratory birds returning to nesting grounds each spring. They may reuse old nests or build new ones.
Cavity nesters, wrens build intricate nests from hundreds of sticks in spaces like abandoned machinery. Despite small cavities, nests are large.
Grown about 5 inches long, the house wren is light brown with blackish wing and tail bars. They live and nest near gardens and houses. Some birdwatchers distinguish males from females by attitude.
