“Sweko itam” (Black Heron), Malay (Meyer 2); “Earappera”, Minahassa (id.). 
“Swekko kaki biru”, “Swekko abu abu sedang”, “Swekko burik ketjil”, Minahassa (N. 0.). 
The following reference apparently proves the occurrence of the migratory E. 
Asiatic B.jaimiiea amure)isis in Celebes: 
d. Butorides macrorhyncha (1) W. Bias., Z. ges. Orn. 1886, 169. 
For further synonymy of B. javanica and its races cf. Salvador!, Orn. Pap. 1882, IH, 359, 
Agg. 1891, 206; Sharpe, Cat. B. 1898, XXVT, 177. 
Adult in breeding plumage. Head above, crest, and a patch on the ear-coverts slatj 
black, glossed with green; remaining parts grey — dark grey on face and neck, 
more slate-grey, partly with strong green reflections, on the lanceolate feathers of 
mantle and scapidars; rump greenish grey, wings and tail-feathers slaty, glossed with 
green, the wing-coverts and inner remiges edged with buff or white; under parts lighter 
grey, white along mesial line of throat and metacarpal edge, stained with buff on 
jugulum (Minahassa, Eaber — C 3546). “Iris light yellow; bill above black; bill 
below, and feet, light green” (Platen, Sarawak: in AV. Bias., .1. f. O. 1882, 254j. 
Apparently the lengthened lanceolate plumes of the back and scapulars are a 
sign of mature age — not simply of nuptial dress, to be lost as soon as the breeding 
season is over. 
Sex. The sexes are not known to differ in plumage. 
Immature. Like the adult, but the wing-coverts more broadly margined with buff and cinnamon, 
the primary coverts and quills conspicuously tipped with white, the lanceolate plumes 
of the back shorter; neck, face and under-parts grey-brown (near Manado C 10952). 
Young. Without the lanceolate dorsal feathers; head above not black, but blackish, streaked 
with cinnamon; upper parts bistre-brown, the wing-coverts broadly edged with cinnamon 
and tipped like the remiges with white or whitish; under parts buff, white on throat, 
broadly streaked with dusky and brown (Tondano — 0 10985).
