Ducks II

The female Northern Pintail is another female duck with a quack-like call (see Ducks I). This bird was with a male on a pond at Lostwood NWR in North Dakota (May).












Several thousand Northern Pintail congregate at Pedricktown Marsh in New Jersey in late winter. The males have a squeaky call and a brrp call (with Canada Goose, Feb, NJ).



On the sonagram there is a tent-like image of the squeaky call above each brrp.












Male burps with female rattling calls (Feb, DE).














The male Green-winged Teal has a brrp call similar to that of the Northern Pintail but a little higher. Note also the rattling calls of the female, similar to those of Northern Pintail but again higher (one hour after sunset, Mar, NJ).












The female has a 4-7 part laughing or decrescendo call (Mar, NJ).

The male Black Scoter courtship call is a mournful whistle. Other sounds include a staccato noise heard during the "forward rush" display, when a male paddles rapidly while crouching low in the water (2,20,43,66,111,145s), and wing whistling (27,34,38,118s).
