Behaviour
The Zapata Rail usually breeds in Cladium jamaicensis sawgrass, building the nest above water-level on a raised tussock. Breeding occurs around September, and possibly also in December and January. American ornithologist James Bond found a nest containing three white eggs 60 cm (2 ft) above water level in sawgrass, but little else is known of the breeding biology. Rails are usually monogamous, and all have precocial chicks which are fed and guarded by the adults.
The animal prefers to feed in sawgrass. The diet is not recorded, but most marsh rails are omnivorous, feeding on invertebrates and plant material. The rails may disperse in the rainy season, returning to permanently flooded areas in the dry months.
Like other rails, this species is difficult to observe as it moves through the sawgrass, and may crouch to avoid detection, but is not usually particularly wary. When disturbed, it may run a short distance and then stop with its tail raised and the conspicuous white undertail showing. Despite its short wings, the Zapata Rail may not be completely flightless. On morphological grounds it would be classed as a flightless species, since the pectoral girdle and wing are as reduced as in other species of rails that are considered to be flightless, but Bond reported that he saw one flutter about ten feet across a canal.

Famous quotes containing the word behaviour:
“I look on it as no trifling effort of female strength to withstand the artful and ardent solicitations of a man that is thoroughly master of our hearts. Should we in the conflict come off victorious, it hardly pays us for the pain we suffer from the experiment ... and I still persist in it that such a behaviour in any man I love would rob me of that most pleasing thought, namely, the obligation I have to him for not making such a trial.”
—Sarah Fielding (1710–1768)
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
