Soft-tissue specimens from pre-European extinct birds of New Zealand [PDF]

open access: yes, 2012
We provide the first complete review of soft tissue remains from New Zealand birds that became extinct prior to European settlement (c. AD 1800). These rare specimens allow insights into the anatomy and appearance of the birds that are not attainable ...

Evolution: Flight of the Ratites [PDF]

open access: yesCurrent Biology, 2017
The flightless ratite birds are scattered all across the Southern hemisphere, on landmasses that have long been separated from each other. But how did they get there? They flew in from the North.

Spontaneous diseases in captive ratites (Struthioniformes) in northwestern Germany: A retrospective study.

open access: yesPLoS ONE, 2017
A retrospective study was carried out to define the spectrum of spontaneous diseases in ostriches and few other captive ratites, order Struthioniformes, in northwestern Germany. The investigation included 71 ratites necropsied between 1968 and 2014. They

A critique of avian CHD-based molecular sexing protocols illustrated by a Z-chromosome polymorphism detected in auklets [PDF]

open access: yes, 2001
The sexes of non-ratite birds can be determined routinely by PCR amplification of the CHD-Z and CHD-W genes. CHD -based molecular sexing of four species of auklets revealed the presence of a polymorphism in the Z chromosome.

Sex determination in ratite and non ratite birds by molecular method

open access: yesThe Indian Journal of Animal Sciences, 2016
In spite of number of methods for sex determination in birds, it is very difficult to distinguish sex especially in ratite birds due to lack of sexual dimorphism. Chromodomain helicase DNA binding 1 gene (CHD 1) is the choice of gene for gender differentiation using PCR based molecular method. In present study, non ratite CHD gene specific primers viz.
