Representative samples are reported from total number of samples examined; for example, only two of four (2/4) feather samples of Pitohui cristatus are reported. Specimens are coded as follows: collection site from list below followed by month/yr and lowercase letters for individual birds. In some cases identical results from several birds are combined. Collection localities of specimens (latitude, longitude): A, Varirata National Park, Central Province, S 9° 9.43′, E 147° 21.9′; B, O'o-Pio, near Haia Village, Chimbu Province, S 6° 6.78′, E 145° 2.2′; C, Crater Mountain Research Station, Chimbu Province, S 6° 6.75′, E 145° 5.6′; D, Kau Wildlife Area, Baitabag Village, Madang Province, S 5° 5.11′, E 145° 47′; E, Nokopo Village, Huon Peninsula, Madang Province, S 5° 5.93′, E 146° 36.0′; F, So-obo, near Haia Village, Chimbu Province, S 6° 6.9′, E 145° 3.66′; G, Bonua Village, Bonua River, Central Province, S 10° 10.0′, E 149° 8.5′; H, Balbe Village, Madang Province, S 4° 4.94′, E 145° 36′; I, Ikamea on Fly River tributary of Elevala River, above Kiunga, Western Province, S 6° 07′, E 141° 33′; J, Ohu Village, Madang Province, S 5° 5.16′, E 145° 39′; K, Kakoro Field Station, Gulf Province, collected by staff of Honolulu Hawaii Zoo; S 7° 41′, E 146° 32′; L, Ilauru, Morobe Province Area, collected by staff of Honolulu Hawaii Zoo, S 7° 25′, E 146° 47′; M, Knjnyk, above Kaironk Village, Central Ranges, Madang Province, S 5° 10.1′, E 144° 29′; N, Bambu village, Finisterre Ranges, Huon Peninsula, S 5° 5.87′, E 146° 31.1′.
