General Species Description: Reproduction Comments:In Texas, egg records extend from early February to mid-October, with a peak between April and August (Johnsgard 1993). Breeding is nearly complete by late June in Colombia; some nesting begins in April in Panama (Hilty and Brown 1986). Clutch size is 2-6 (reportedly usually 4 but mean 2.9 in Texas). Incubation averages about 24-25 days. Young are tended by both sexes (Palmer 1962), independent by 12 weeks. Renests if clutch is lost. In Texas, 43% of chicks fledged (see Johnsgard 1993). Ecology Comments:Sociable, but more often alone or in pairs along forested rivers (Hilty and Brown 1986). Typically forages singly. In Argentina, young dispersed mainly within 650 km of natal site (see Johnsgard 1993). In Texas, raccoons and boat-tailed grackles prey on eggs and young.
