ARDEID2E — THE HERONS — ARDEA.

6.50-7.00 inches ; tarsus, 8.50-9.00 inches), lighter general coloration, ancl (in dried skin) light 
brown instead of black legs. Dichromatic ; the white phase being indistinguishable from that of 
A. occiclentalis (?). 
Adult $ (No. 82,329, U. S. Nat. Mus., Oyster Bay, Florida, March, 1881 ; Charles W. Ward) : 
Head white, with the sides of the crown and entire occiput (including the lengthened plumes) 
deep black ; neck lavender-gray (much lighter than in the type of JViirdemanni), the fore-neck 
white, thickly streaked with black for the lower two thirds ; jugular plumes chiefly white, their 
lengthened tapering portion entirely so. Upper surface uniform bluish plumbeous, the lengthened 
scapular plumes hoary whitish or pale silvery gray. Upper breast uniform black ; abdomen and 
lower breast white, rather indistinctly streaked with dark gray ; anal region mixed black and 
white, in longitudinal dashes (the black rather predominating) ; erissum immaculate pure white. 
Tibiae uniform light cinnamon ; edge of the wing (especially near the bend) deeper cinnamon, but 
this much mixed with white toward the bases of the quills ; lining of the wing, axillars, sides, 
and flanks, uniform plumbeous. Bill, apparently, entirely olivaceous-yellow ; naked portion of 
tibiae very pale brown (evidently yellowish or flesh-colored in life) ; tarsi light brown (olivaceous 
in life ?), darker in front ; toes light brown. Wing, 20.50 ; culmen, 6.75 ; depth of bill through 
nostril, 1.10 ; tarsus, 8.75 ; middle toe, 5.10 ; naked portion of tibiae, 5.50. 
Mr. W. H. Collins, of Detroit, who kindly presented the specimen described above to the Na- 
tional Museum, has sent measurements of two other specimens, one in his own possession, the 
other mounted for Mr. Ward. As may be seen below, they agree closely in dimensions with the 
type, their measurements being, respectively, wing, 20.00-20.50 ; culmen, 6.50-7.00 ; depth of bill 
through nostril, 1.25 ; tarsus, 8.75-9.00 ; middle toe, 5.25-5.45 ; naked portion of tibia, 5.75-6.00. 
The following facts in relation to this apparently distinct species or race of large 
Heron is substantially the same as that printed in the original account cited above. 
The specimens described were obtained by Mr. Charles W. Ward, of Pontiac, Mich- 
igan, who spent several weeks at the breeding-grounds of the bird in question, and 
was thus enabled to make many very interesting observations on its habits, etc. Mr. 
Ward’s memoranda, which are especially interesting in connection with the question 
of Ardea occidentalism Aud., and A. Wurdemanni, Baird, are as follows : — 
“ My observations of the Herons during the past season do not correspond with 
those of Mr. N. B. Moore, as recorded on page 232 of your article, 1 in regard to their 
feeding habits. I found them generally living in communities, roosting, nesting, and 
feeding together, like Pigeons, and often observed flocks of the Little White, Reddish, 
and other Egrets, feeding together like Teal Ducks. Two specimens of A. occidentalis 
were seen feeding quietly within twenty feet of one of the Herons procured by me 
[A. Wardi, nobis]. They were feeding on a mud-bar at low tide. I was once con- 
cealed in the low brush near a small pool watching three Louisiana Egrets chasing 
minnows, when two of them making for the same minnow squared off for a knock- 
down, while the third coolly appropriated the prize, leaving the combatants situated 
like complainant and defendant at the close of a lawsuit. In all my observations of 
the Herons l have seen nothing to lead to a conclusion that one of these birds held 
any particular antipathy against its own species while feeding. In the many squab- 
bles between Herons on their feeding-grounds, the encounters occurred quite as often 
between different species as members of the same species. It may be that during 
the breeding season they are more friendly than at other times. In order that you 
may understand my opportunities for observing these birds, I inclose a rough map of 
Mound Key and surroundings, my camping-place from January 20 till April 10. As 
you will see by the figures marked .... it was in the midst of their feeding-grounds, 
these places being mud- and sand-bars, bare- at low tide. Regarding the Reddish 
Egret, among many thousands of them I saw only one in the pure white plumage,
