Why woodpeckers drum on trees and gutters in spring

Why this time of year

Mass Audubon says Downy and Hairy Woodpeckers drum on trees year-round, but drumming picks up as they set up territories in late winter and is most common in spring. A Mass Audubon bird expert puts the start of the loud drumming in March and April.

How to notice it

1. On a still morning, listen for a burst of rapid knocks so fast they blur into one rattle, often coming from a dead branch, a hollow trunk or a metal gutter or flashing.
2. Listen to what comes next. A drum is a short burst, then a pause, then another burst from the same spot. Pecking for food sounds different: more methodical knocks, without the fast rolling burst.
3. If the burst is very fast with a long wait between drums, it may be a Hairy Woodpecker. A slower roll with only a few seconds between drums points to a Downy.
4. If one is drumming on your house, it is signaling, not eating the house: drumming on a home rarely does any real damage, and it can go on for several weeks in early spring.

Verbatim: 'Both species will drum on trees year-round to communicate but the frequency picks up this time of year as they set up territories.' Also: 'Hairy Woodpeckers drum very fast with long pauses - at least 25 taps/ second; 20 seconds between - while Downy Woodpeckers drum more slowly with shorter pauses - 15 taps/second; a few seconds between.' (The page uses em dashes there; swapped for ' - ' in this note.) Supports 'picks up' rather than 'begins', February timing (the post date is 'this time of year'), and the two species rates exactly as given.

• massaudubon.orgMass Audubon woodpeckers page (primary, permanent). Verbatim: 'Drumming, on the other hand, is what a woodpecker does to attract a mate or mark its territory by alerting the competition.' 'Drumming occurs most commonly in spring.' 'In the spring and fall, especially, one can hear the distinct sound of a woodpecker drumming or drilling nearby.' Downy: 'as in many woodpeckers, it drums on trees rather than singing a song.' On houses: 'the birds frequently choose it as drilling or drumming sites.' Also: 'Leave dead trees and snags around the yard to help provide natural feeding, nesting, and drumming sites.' The only morning wording is about drilling on houses: 'before it gets settled in to work in the mornings'.
• portal.ct.govConnecticut DEEP Wildlife Division (primary, state agency, Northeast). Verbatim: 'Drumming by the male is a territorial behavior done to attract a mate and establish a territory.' Typical surface: 'Typically, the drumming surface is a hollow tree'; woodpeckers 'may also use metal gutters, chimney flashing, or aluminum or wood siding.' 'Drumming rarely results in any significant damage to the home' but 'it can be an annoyance for the human occupants that may last for several weeks in early spring.' 'Spring is the most active period as woodpeckers are both drumming and drilling.' Drumming and drilling 'may occur in fall or spring.'
• bostonglobe.comBoston Globe Field Guide column by Don Lyman, 2019-03-29 per the URL (secondary, newspaper; it reports Wayne Petersen, Mass Audubon's Director of Important Bird Areas). The author's own sentence, which reports Petersen's information but sits outside his quotation marks: 'Increasing temperatures and light prompt male woodpeckers to start loud drumming in March and April.' Petersen quoted: 'The males are advertising for females, and letting other woodpeckers know it's their territory.' and 'Woodpeckers are not as animated with their drumming when they're just using their beaks to look for food.' Supports March and April in Massachusetts and the warming/light trigger.
• audubon.orgNational Audubon field guide (primary). Verbatim: 'Male and female take turns drumming loudly on dead limbs on their separate territories; male gradually approaches.' Pairs form 'by late winter.' Supports both sexes drumming (Downy) and dead limbs as the drum.
• audubon.orgNational Audubon field guide (primary). Verbatim: 'Courtship includes both birds drumming in duet and the ritualized tapping at symbolic nest sites by the female.' Pairing happens 'in mid-winter'. Supports both sexes drumming (Hairy).
• audubon.orgAudubon/BirdNote script, 2018-03-05 (secondary, not region-specific). Verbatim: 'Early spring resounds with the percussive hammering of woodpeckers.' Drumming 'broadcasts to other woodpeckers over a long distance a clear assertion of territorial and mating rights.' 'it might just find that your metal rain-gutter makes the best music.' Downy's drum roll is 'rather short and not too fast.' Feeding taps: 'these whacks are more methodical.'
• nepm.orgNew England Public Media, 2017-06-02 (secondary, Massachusetts public radio, quoting retired UMass ornithologist Don Kroodsma). Verbatim: 'In late winter, males drum to claim a territory.' 'Both males and females can drum to attract a mate or to tell each other their location.' 'Some species of woodpeckers drum on gutters and other found objects.' 'Woodpeckers' drumming can be heard until about the end of June.' Supports late-winter onset in the region and is the only source found for May (and June).
