Thus, unmonitored purple martin houses are often overtaken by more aggressive, non-native species. [17], Fall migration is also staggered, as birds head south when the breeding season is over. Especially effective when used along with decoys. Purple martins are fairly noisy, chirping and making sounds that have been described as chortles, rattles, and croaks. [3], These flocks can be so large that when they take-off from these roosts to forage the activity is detected on Doppler radar as rings. In many places, humans put up real or artificial hollow gourds, or houses for martins, especially in the east, where purple martins are almost entirely dependent on such structures. During courtship, males make a croak song that can be 4 seconds long; he only does this when a female is nearby, often before dawn and from inside the nest cavity. Adult females are dark on top with some steel blue sheen, and lighter underparts. Older males typically migrate first and leave the overwintering sites in late December or early January, followed by older females.
