Blue-footed booby
The blue-footed booby is a specialized fish eater, feeding on small schooling fish such as sardines, anchovies, mackerel, and flying fish. It will also take squid and offal. The blue-footed booby hunts by diving into the ocean after prey, sometimes from a great height, and can also swim underwater in pursuit of its prey. It can hunt singly, in pairs, or in larger flocks. Boobies travel in parties of about 12 to areas of water with large schools of small fish. When the lead bird sees a fish shoal in the water, it will signal to the rest of the group and they will all dive in unison, pointing their bodies down like arrows.
Blue-faced honeyeater
The blue-faced honeyeater was first described by ornithologist John Latham in his 1801 work "Supplementum Indicis Ornithologici, sive Systematis Ornithologiae". However, he described it as three separate species, seemingly not knowing it was the same bird in each case: The blue-eared grackle ("Gracula cyanotis"), the blue-cheeked bee-eater ("Merops cyanops"), and as the blue-cheeked thrush ("Turdus cyanous"). It was as the blue-cheeked bee-eater that it was painted between 1788 and 1797 by Thomas Watling, one of a group known collectively as the Port Jackson Painter. It was reclassified in the genus "Entomyzon", which was erected by William Swainson in 1825, who observed the "Blue-faced Grakle" as the only insectivorous member of the genus and posited it was a link between the smaller honeyeaters and the riflebirds of the genus "Ptiloris". The generic name is derived from the Ancient Greek "ento-/εντο"- ("inside") and "myzein/μυζειν" "to drink" or "suck". The specific epithet, "cyanotis", means "blue-eared" and combines "cyano-/κυανο"- "blue" with "otis", a Latinised form of "ωτος", the Greek genitive of "ous/ους" "ear". Swainson spelt it "Entomiza" in an 1837 publication, and George Gray wrote "Entomyza" in 1840.
