circle of the face, black, finely marked with small, curving spots of 
white; back and wings, dark brown, sprinkled and xpotted with white, 
pale ferruginous, and dusky; primaries, barred with brownish yellow 
and dusky, darkening towards the tips; secondaries, more finely barred 
and powdered with white and dusky ; tail, rounded at the end, of the 
same length with the wings, beautifully barred and marbled with dull 
white and pale rusty, on a dark brown ground; throat, snd breast, 
clouded with rusty, cream, black and white ; belly, beautifally streuled 
with large arrow-heads of black; Iegs and thighs, plain pale rusty, 
feathered to the claws, which are blue black, large, ond sharp; inside 
of the wing, brownish yellow, with a large spot of black af. the root, of 
the primaries. Jig. 202 was a female. Of the male IT cannot spevk 
precisely ; though, from the number of these birds which { have exiin- 
ined in the full, when it is difficult to ascertain their sex, J conjecture 
that they differ very little in color. 
About six or seven miles below Philadelphia, and not far from the 
Delaware, is ao low swamp, thickly covered with trees, and inundated 
during preat part of the year, This place is the resort of great num- 
bers of the (Qlua-Bird, or Night Raven, (Ardea nycticoraz,) where they 
build in large companies. On the 25th of April, while wading among 
the dark recesses of this place, observing the habite of these birds, F 
discovered a Long-eared Owl, which had taken possersion of one of 
their nesta, and was sitting. On mounting to the nest, fF found it con- 
tained four evga; and, breaking one of these, the young appeared al- 
inost ready to leave the shell. ‘Phere were numbers of the (luna-Pirds? 
nests on the adjoining trees a] around, and one of them actually on 
the same tree. Thus we see how unvarying are the mannera of this 
species, however remote and different the countries may be where it 
has taken up its residence.

Tue figure of this bird, (No. 205,) and those of Nos. 206 and 207, 
are offered to the public with a confidence in their fidelity ; but these, 
I am sorry to say, are almost all 1 have to give towards elucidating 
* The Red-tailed Guzzard is a sperics peculiar to America, and, in its adult 
state,seems perfectly known to ornithologids. Vhe figure on the same plate, and
