King of Saxony bird-of-paradise

The King of Saxony bird-of-paradise (Pteridophora alberti) is a bird in the bird-of-paradise family (Paradisaeidae). It is the only member in the monotypic genus Pteridophora. It is endemic to montane forest in New Guinea.

The exact limits of the family have been the subject of revision as well. The three species of satinbird (the genera Cnemophilus and Loboparadisea) were treated as a subfamily of the birds-of-paradise, Cnemophilinae. In spite of differences in the mouth, foot morphology and nesting habits they remained in the family until a 2000 study moved them to a separate family closer to the berrypeckers and longbills (Melanocharitidae). The same study found that the Macgregor's bird-of-paradise was actually a member of the large Australasian honeyeater family. In addition to these three species, a number of systematically enigmatic species and genera have been considered potential members of this family. The two species in the genus Melampitta, also from New Guinea, have been linked with the birds-of-paradise, but their relationships remain uncertain, more recently being linked with the Australian mudnesters. The silktail of Fiji has been linked with the birds-of-paradise many times since its discovery, but never formally assigned to the family. Recent molecular evidence now places the species with the fantails.

The Green Heron

 The Green Heron

The green heron (Butorides virescens) is a small heron of North and Central America. Butorides is from Middle English butor "bittern" and Ancient Greek -oides, "resembling", and virescens is Latin for "greenish.
 It was long considered conspecific with its sister species the striated heron (Butorides striata), and together they were called "green-backed heron". Birds of the nominate subspecies (no matter which taxonomic arrangement is preferred) are extremely rare vagrants to western Europe; individuals from the Pacific coast of North America may similarly stray as far as Hawaii.
 The habitat of the green heron is small wetlands in low-lying areas. The species is most conspicuous during dusk and dawn, and if anything these birds are nocturnal rather than diurnal, preferring to retreat to sheltered areas in daytime. They feed actively during the day, however, if hungry or provisioning young. Shore-living individuals adapt to the rhythm of the tides. They mainly eat small fish, frogs and aquatic arthropods, but may take any invertebrate or vertebrate prey they can catch, including such animals like leeches and mice. Green herons are intolerant of other birds – including conspecifics – when feeding and are not seen to forage in groups. They typically stand still on shore or in shallow water or perch upon branches and await prey. Sometimes they drop food, insects, or other small objects on the water's surface to attract fish, making them one of the few known tool-using species. This feeding method has led some to title the green and closely related striated heron as among the world's most intelligent birds. They are able to hover briefly to catch prey.
