WEIGHTS, HEMATOLOGY, AND SERUM CHEMISTRY OF 7 SPECIES OF FREE-RANGINGTROPICAL PELAGIC SEABIRDS

I established reference values for weight, hematology, and serum chemi stry for seven species of free-ranging Hawaiian tropical pelagic seabi rds comprising three orders (Procellariiformes, Pelecaniformes, Charad riiformes) and six families (Procellariidae, Phaethontidae, Diomedeida e, Sulidae, Fregatidae, and Laridae). Species examined included 84 Haw aiian dark-rumped petrels (Pterodoma phaeopygia), 90 wedge-tailed shea rwaters (Puffinus pacificus), 151 Laysan albatrosses (Diomedea immutab ilis), 69 red-footed boobies (Sula sula), 154 red-tailed tropicbirds ( Phaeton rubricauda), 90 great frigatebirds (Fregata minor), and 72 soo ty terns (Sterna fuscata). Hematocrit, total plasma solids, total and differential white cell counts, serum glucose, calcium, phosphorus, ur ic acid, total protein, albumin, globulin, aspartate aminotransferase and creatinine phosphokinase were analyzed. Among and within species, hematology and chemistry values varied with age, sex, season, and isla nd of collection. Despite this variation, order-wide trends were obser ved.
