Lovette and Bermingham explored the temporal structure of Dendroica diversification via a phylogeny based on nucleotides of protein-coding mitochondrial DNA mtDNA. Phylogenetic results indicated that the Eurylaimides consist of two monophyletic groups, the pittas Pittidae and the broadbills Eurylaimidae sensu latoand that the broadbills consist of two highly divergent clades, one containing the sister genera Smithornis and Calyptomena, the other containing Pseudocalyptomena graueri, Sapayoa aenigma, the asity genera Philepitta and Neodrepanis, and five Asian genera.

Chickadee language -- Black-capped Chickadees Poecile atricapilla have a complex language for warning flock-mates about predators. So after a swim it shakes its body, much like a dog does, to get rid of water.

However, it is very brave and will stand its ground if approached. Sometimes the seeds are so large that no other animal can swallow and disperse them.

It also has a sharper sense of smell than most birds which makes it easier for this bird to locate food in leaf litter and in dense forest.

Given the marked differences in plumage characters, sexual selection may have acted as the mechanism of divergence Distribution of nearest congeneric neighbor distances in COI i.

This awesome bird belongs to an ancient lineage and is one of the most striking of the flightless birds; its conservation therefore has important cultural and ecological significance. Casuariidae cassowaries and emus Conservation status: Cassowary chicks, when about nine months old, must find their own territory.

Energetic cost of singing - Sexually selected displays, such as male passerine bird song, are predicted to be costly.

This has assisted the evolution of some 40 species of birds-of-paradise. Habitat Loss Large tracts of rainforest, home to these unique birds, has been chopped down for timber, banana and sugar-cane plantations and for urban developments.

Both species produced sounds near the floor of the human hearing range in their pulsed booming notes: Casuarius casuarius johnsonii Family: It can also jump as high as 2 meters m 6ft.

The most obvious being for mating. One population in the Wet Tropics and two populations in Cape York. The government sponsored the immigration of Filipinos in the s to provide workers in skilled professions, and many entered business and intermarried locally.

There are three extant species. The most common of these, the southern cassowary, is the third-tallest and second-heaviest living bird. Casuariidae - Cassowaries Southern Cassowary Casuarius casuarius ©HL & KD Snyder Website.

The cassowaries are ratites (flightless birds without a keel on their sternum bone) in the genus Casuarius and are native to the tropical forests of New Guinea, nearby islands, and northeastern Australia.

The Tertiary ‘big bang’ model for modern bird evolution. A near total demise of archaic birds occurred at the K–T boundary, with a rapid reorganization and explosive early Tertiary evolution from a bottleneck of modern ornithurine morphological types, perhaps involving ‘transitional shorebirds', paleognaths and some other lineages.

Papua New Guinea - Climate: Although all the climatic regions of Papua New Guinea are basically tropical, they are nevertheless varied.

In the lowlands, mean annual maximum temperatures range from about 86 to 90 °F (30 to 32 °C), and the minimums are between 73 and 75 °F (23 and 24 °C). a system seldom found among the Melanesian.

The cassowaries are ratites (flightless birds without a keel on their sternum bone) in the genus Casuarius and are native to the tropical forests of New Guinea, nearby islands, and northeastern Australia. There are three extant (existing) species recognized today.

The most common of these, the southern cassowary, is the third tallest and second heaviest living bird. Found in north-eastern Australia, Papua New Guinea and the Aru and Seram Islands Cassowaries are found in three broad populations in north-eastern Australia: Cape York (far northern population): far northern Cape York Peninsula, centred on the much less extensive vine forests of Lockerbie and McHenry Uplands.
