Icterid flight calls I : Blackbirds

Red-winged Blackbirds have a variety of calls that are given in flight and while perched. Recordings are of perched birds unless noted.
The common check call (Apr, NJ).














Compare with the very similar call of the Rusty Blackbird (Apr,NJ).












Tup, another commonly heard flight call (with Song Sparrow call and Yellow Warbler song in background)
(Apr, NJ)










Birds in flight, with several different calls (Mar, NJ).

hard chp at beginning of recording









tek 5-11s








chuks start at 12s










whistle










The pwik call is apparently only given by female Red-winged Blackbirds (Evans and O'Brien). It sounds quite similar to the tup call but has a different sonagram. It is also regularly given in flight (Nov, NJ).












The common flight call of the Rusty Blackbird (also often given perched) is very similar to the check of Red-winged Blackbirds.
Female calling, Common Grackle singing in background (Feb, NJ).











These five birds gave a liquidy gup call in a tree before they flew off towards the end of the recording (Dec, NJ). Birds often give different calls just before or after taking flight than those given in sustained flight. Compare with the higher tup call of the Red-winged Blackbird.










The Brewer's Blackbird flight call is a hard tuk (July, CO).













A small group of Brewer's Blackbirds, a rare bird in the east, has been found on a cattle farm in Salem County, NJ in recent years. This is a recording of their flight call (Jan).












Common Grackles also have a frequently heard chack call that is lower than that of Rusty and Red-winged Blackbirds (June, NJ)


(Feb, NJ)













Boat-tailed Grackle "chut" flight call (perched male, Nov, NJ).











Male Brown-headed Cowbirds have what is called a flight whistle, often given while perched, which is multisyllabic (bird calling from tree-top, May, PA).

edited to show the three phrases











Another male call is termed the single syllable flight call. In this case it is a pewee-like call, given by a lone male from the top of a tree in the NJ pine barrens (June).
time scale reduced











The check or chuck calls of Red-winged Blackbird, Rusty Blackbird and Common Grackle are difficult to tell apart. Here they are together:
Red-winged Blackbird
Rusty Blackbird

Common Grackle



The Bobolink also has a chuck call (not a flight call, more of an alarm call), low like that of the Common Grackle, and less commonly heard during migration than the calls of the other three species.
(migrant, Sep, NJ)



Red-winged Blackbird (highest call)









Rusty Blackbird










Common Grackle (a lower call)










Bobolink (the lowest call)
