All three species mentioned in this article breed on these islands, but the Piratic Flycatcher employs a truly piratic strategy: the breeding pair targets a recently built woven nest, often by a Yellow Oriole or Yellow-rumped Cacique but they have also been recorded targeting the nests of other flycatchers.

The highly specialized foraging strategy of flamingos makes them vulnerable to the effect of subtle changes in habitat quality. Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale.

Both pelicans have a very specialized foraging strategy that depends on abundant fish near the surface. Some pesticides killed pelicans directly, while DDT contamination led to thin-shelled eggs that broke under the weight of the parents. Abandoned fishing line also threatens pelicans along with many marine animals.

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.
