Birds of the Darwin Region is the 1st entire remedy of the avifauna of Darwin, a urban positioned in Australia’s monsoon tropics, the place seasons are outlined through rainfall instead of via temperature. With its mangrove-lined bays and creeks, tidal mudflats, monsoon rainforests, savannah woodlands and freshwater lagoons, Darwin has retained all of its unique habitats in near-pristine , and is domestic or host to 323 poultry species. not like different Australian towns, it has no confirmed unique poultry species.

Basic sexual features, these constructions and methods at once fascinated about copy, are probably the most varied, really good, and weird within the animal country. in addition, reproductive characteristics are usually species-specific, suggesting that they developed very swiftly. This range, lengthy the province of taxonomists, has lately attracted broader curiosity from evolutionary biologists, in particular these drawn to sexual choice and the evolution of reproductive ideas.

21. Map of Darwin region grid cells showing number of surveys (upper value) and number of species (lower value) for each cell. The physical features in the background (based on Fig. 7) provide context for the uneven spatial distribution of surveys. Note the lack of surveys in the northeast corner (due to difficulties of access). these sources of bias, we have endeavoured to compensate for the seasonal bias in sampling by calculating a reporting rate for each species, based on the following simple formula: monthly reporting sum of records of species A in month 100 = rate for species A sum of surveys for month To further highlight seasonality, different coloured bars are used to represent Wet season months and Dry season months, although it should be noted that these seasons grade into each other during the Build-up and Wet–Dry transition periods (see Introduction: Climate).

Traditional terms such as ‘common’ and ‘rare’ are used to imply both abundance and spatial distribution. Residents are here defined as those species or populations in which the majority of adults are thought to be sedentary, spending their whole lives in a relatively small area. Thus residents are expected to breed in the region. In contrast, migrants are species that are known to undertake long-distance movements from their breeding grounds to wintering grounds every year. Most such birds do not breed in Australia, but there are some exceptions, as discussed in the next section.
