FLAMINGOES, Ducks, AND SCREAMERS,— 
Orders OpontToGLossI, ANSERES, AND PALAMEDEZ. 
TAKING the general term “ducks” as including the geese, swans, etc., the members 
of the three groups above named will comprise the remaining orders of birds 
with bridged (desmognathous) palates, all of which are broadly distinguished from 
those hitherto described by the circumstance that their young are covered with 
down when hatched, and are able to run within a few hours of their first appear- 
ance in the world. The members of these three orders are accordingly the only 
birds which have bridged palates, and “precocious” young. In regard to the 
flamingoes, it has only been recently ascertained that the young are hatched in 
this forward condition. In the collective group the three front toes are either 
completely webbed, or united by a fold of skin; and in most cases the beak is 
either depressed and expanded, or has its extremity so bent down as to be at right 
angles to its base, while its angle is produced in a recurved process behind the 
points of articulation with the skull. Generally the rostrum of the base of the 
skull has oval basipterygoid facets placed relatively far forwards; and in all 
cases the oil-gland is tufted. Many of the group are more or less completely 
herbivorous. . 
THE FLAMINGOES. 
Order ODONTOGLOSSI,—Family PH@NICOPTERIDZ. 
With an apparently intuitive perception of its zoological relationship, the 
Persians apply the name of kaj-i-surkh (red goose) to the flamingo, and have 
thus forestalled the ornithologist, by whom these birds were always associated 
with the storks and herons, as indeed they still are by some. Possessing the above- 
mentioned features in common with the other two groups treated in this chapter, 
the flamingoes, if we had only existing forms to deal with, might be readily 
distinguished by the peculiar form of their beaks; but it happens that there are 
certain nearly allied extinct birds in which the beak appears to have been of a 
more normal form; and we are accordingly compelled to rely largely on other 
features in defining the order. The whole group is readily characterised 
by the great length of the legs, in which the tibia may be not greatly 
longer than the metatarsus, while the first toe is rudimentary, or even 
wanting. The lower end of the tibia differs widely from that of the duck 
tribe in that its lower end is not bent inwards; while the corresponding 
extremity of the metatarsus is very similar to that of the storks, having
