Trochet, John 1991 Catalogue On this initial field outing of the 1991 season, I forgot my catalogue from the previous two years. I cannot recall my last entry number, but it was in the 230-240 range, I believe. I am therefore starting this series at #250. Certainly 250 is not a duplicate number. As with last year's entries, the abbreviation "STD" indi- cates standard sex part color appropriate to sex. A reminder of what these are follows. For adult males: iris dark sepia brown; maxilla dark gray, greener proximally, tip black; mandible yellowish-gray proximally, with a dusky tip; anterior gonyx yellow- isk; loze medium-dark grayish brown, lores slightly darker and slightly grayer; Claws medium gray; mouth lining pale yellowish; Throat flesh-pink. For adult females, only bill colors differ: mandib- maxilla ule dull med-dark gray with a darker tip. Mandible all dusky. Variations from these will be noted on individual entries. Other abbrevia-tions: x-except; c-with; f-without; o-otherwise; RR-retained remiges; Ps-primary st Chey Ranch adjacent to Quarry Section of Dinosaur National Monument Uinta County, Utah.
