This paper presents a suite of user-friendly computer programs designed for univariate analysis of measurements of sexually size dimorphic birds which have not been sexed by other means. Two of the programs estimate the measurement parameters for each sex (number, mean, standard deviation) and two use these estimates to produce a sexing criterion or rule […]
Diel temporal vocalisation patterns in the Mistletoe Bird (Dicaeum hirundinaceum) and seasonal abundance relative to the flowering and fruiting of the Mistletoe Dendrophthoe vitellina.
