This paper documents and maps the distributions within Diamantina National Park, Queensland, of 180 bird species based on our database of 16 127 individual species records gained during 15 visits to the Park from 1994 to 2009. In addition to our sightings we document the occurrence in the Park of three other species - Letter-winged Kite Elanus scriplus, Plains-wanderer Pedionomus torquaius and Night Parrot Pezoporus occidentalis - recorded by others but not seen by us. Our distribution records are based on species presence/absence in grid blocks of 1 minute of latitude × 1 minute of longitude, and are mapped accordingly. We also recorded and mapped observations of breeding. Other information collected opportunistically related to bird casualties resulting from collisions with barbed-wire fences, and dietary information for selected species derived from analysis of regurgitated pellets. The Park bird list includes 11 species listed as threatened, which emphasises the value of a well-managed Diamantina National Park as a conservation reserve. Removal or modification of barbed-wire fences and ongoing control of straying or trespassing domestic stock will enhance this value. Continuing bird monitoring in the Park will assist in management of the Park. We were greatly assisted in our work by the logistical support of Queensland Parks & Wildlife Service staff; otherwise, the work was carried out at the expense of the participants, and represents about half a million dollars of value over 15 years.

We collated sightings of the Pictorella Mannikin Heteromunia pectoralis since 31 July 2002 that occurred outside the range of the species, as recorded during the 4 years of data collection for The New Atlas of Australian Birds (1998-2002). The widespread nature of the records suggests an irruption of the species.

The diet of the Eastern Barn Owl Tyto (javanica) delicatula was determined by analysis of 185 pellets from a roost in Diamantina National Park, Queensland, collected in March-April and September 2008 and May 2009. The diet comprised 47% mammals (17.5% dasyunds, 29.5% rodents), 7% birds, <1% lizards, < 1% frogs, and 45% insects by number, and 80% mammals (24% dasyurids, 56% rodents), 15% birds, < 1% lizards and frogs, and 5% insects by biomass. Some new records of native mammals (two dasyurids, three rodents) were obtained for Owl pellets from within the Park.
