2008 journal article
A novel field evaluation of the effectiveness of distance and independent observer sampling to estimate aural avian detection probabilities
Journal of Applied Ecology, 45(5), 1349–1356.
author keywords: avian point counts; aural detections; detection probability; distance sampling; field tests; multiple observers
TL;DR:
A field validation of distance and double-observer methods of estimating detection probabilities on aural avian point counts and encourages ecologists working with sampling methods to develop similar methods of working with simulated populations through use of technology.

2007 journal article
A field evaluation of distance measurement error in auditory avian point count surveys
JOURNAL OF WILDLIFE MANAGEMENT, 71(8), 2759–2766.
author keywords: abundance; auditory detections; bird surveys; distance estimation; measurement error; point count surveys
TL;DR:
Findings, which are based on realistic field conditions, suggest measures of uncertainty in distance estimates to auditory detections are substantially higher than assumed by most researchers, which means aural point count estimates of avian abundance based on distance methods deserve careful scrutiny because they are likely biased.

Experimental analysis of the auditory detection process on avian point counts
AUK, 124(3), 986–999.
author keywords: ambient noise; detection probability; measurement error; point counts
TL;DR:
Some of the inherent difficulties in interpreting avian abundance estimates based on auditory detections are illustrated, and why estimates that do not account for variations in detection probability will not withstand critical scrutiny are illustrated.

Factors affecting aural detections of songbirds
ECOLOGICAL APPLICATIONS, 17(3), 948–955.
author keywords: auditory detection; detection probability; observer differences; point counts; singing rate; species difference; warblers
MeSH headings : Animals; Auditory Perception; Humans; Observer Variation; Population Density; Reproducibility of Results; Songbirds / physiology; Vocalization, Animal
TL;DR:
The findings of this study strongly support the importance of adjusting measures of avian diversity or abundance from auditory point counts with direct estimates of detection probability.

2007 journal article
Local annual survival and seasonal residency rates of semipalmated sandpipers (Calidris pusilla) in Puerto Rico
AUK, 124(4), 1397–1406.
author keywords: apparent survival; Calidris pusilla; Caribbean; mark-recapture; migration; Semipalmated Sandpiper; stopover; winter distribution
TL;DR:
Seasonal residency and local annual survival rates of migratory Semipalmated Sandpipers at the Cabo Rojo salt flats, Puerto Rico, support the inclusion of the Caribbean as part of the species' winter range and suggest that birds replenish some spent fat reserves and strive for energetic maintenance.

Multiple-species analysis of point count data: a more parsimonious modelling framework
JOURNAL OF APPLIED ECOLOGY, 44(2), 281–290.
author keywords: abundance; capture-recapture; multiple-species modelling; point count surveys; population surveys
TL;DR:
A multiple-species modelling framework that uses similarities in capture/detection processes among species to model multiple species data more parsimoniously is developed and is applicable to a wide range of sampling techniques and taxa.

Estimating detection probabilities from multiple-observer point counts
AUK, 123(4), 1172–1182.
author keywords: bird surveys; capture-recapture; detection probability; multiple observer; point counts
TL;DR:
Although independent-observer methods are expensive and impractical for large- scale applications, it is believed they can provide important insights into the sources and degree of perception bias in avian point-count estimates and may be useful in a two-stage sampling framework to calibrate larger surveys based on single-ob server estimates.

Aerial surveys and the potential biological removal technique indicate that the Torres Strait dugong fishery is unsustainable
ANIMAL CONSERVATION, 7, 435–443.
TL;DR:
Estimates of a sustainable harvest are so far below the current harvest that it must be unsustainable and governments should heed the Islanders' requests for assistance in implementing co‐management of the fishery as a matter of urgency.
