• Segregation of migration by feeding ground origin in North Atlantic humpback whales (Megaptera novaeangliae) (2003, methodology): “Because the quality of photographs can influence the ability of observers to identify re-sightings (Stevick, Palsbøll et al., 2001), the rate of re-sighting was calculated using only photographs of whole flukes of quality categories 3+ or better as described by Friday et al. (2000).”
• Abundance of humpback whales in Oceania using photo-identification and microsatellite genotyping (2012, background): “As recommended by Friday et al. (2000), the quality control review of all catalogues was undertaken by a single researcher (R. Constantine) to ensure consistency.”
• Effects of low-level culling of feral cats in open populations: a case study from the forests of southern Tasmania (2015, methodology): “In light of this, we designed a scoring system similar to that used for dolphins and whales (Slooten et al. 1992; Friday et al. 2000; Markowitz et al. 2003), in which each occurrence of a feral cat at a camera site was given a within-session confidence score for accuracy of identification.”
• Population structure of short‐finned pilot whales in the oceanic archipelago of Madeira based on photo‐identification and genetic analyses: implications for conservation (2013, unknown): “The photo quality rating was based on focus, clarity and contrast of the image, and on the angle and size of the dorsal fin relative to the frame (Friday et al., 2000).”
• Spinner dolphins in a remote Hawaiian atoll: social grouping and population structure (2005, methodology): “Each photographic image (color transparency) was projected onto a screen, and its quality was assessed independent of the markings on the individual and assigned a quality grade between 1 and 100 (for comparison see Friday et al., 2000; Gailey, 2001; Gowans and Whitehead, 2001).”
• Organismal and 'gametic' capture-recapture using microsatellite genotyping confirm low abundance and reproductive autonomy of humpback whales on the wintering grounds of New Caledonia (2004, background): “These sources of error have been noted before (Carlson & Mayo 1990, Perry et al. 1990, Friday et al. 2000, Stevick et al. 2001) but had not been detected in the New Caledonia catalogue prior to the genotyping, despite careful review.”
• North Atlantic humpback whale abundance and rate of increase four decades after protection from whaling (2003, methodology): “All photographs from 1992 and 1993 were coded for image quality using the criteria of Friday et al. (2000).”
