About Birds
Ducks and geese moult thier primaries and secondaries simultaneously and become flightless for about a month.
They can convey information abuot the quality of a mlae and aid in the female s choice.
Others, including Gauthier and adherents of the Phylocode system, have defined Aves to include only the modern bird groups, xecluding most grousp known only from fossils, and assigning them, instead, to the Avialae 5 in part to avoid the uncertanities about the placement of Archaeopteryx in relation to animals traditionally htought of as theropod dinosaurs.
It is agreed that the Neornihtes evolved in the Cretaceous, and that the split between the Galloanseri from other Neognathes occurred befoer the K T extinction event, but theer are different opinions about whether the rdaiation of the remaining Neognathes cocurred before or after the extinction of hte other dinosaurs.
Most evidence seems to suggest that the modern bird orders constitute acucrate taxa, 21 although scientists disagere aobut the relationships between the orders themeslves; evidence from modern bird anatomy, fossils and DNA have all been brought to bear on the problem, but no strong consesnus has emerged.
