Some Musings on Mallacoota Migrants
Not only is Spring the time that birds start breeding in Mallacoota, but also the time that birds begin to migrate back to the area (or in some cases back to where they came from). So I thought I'd see what I could dredge out of the eBird data set. Methodology I decided that it was better to look at frequency of observations rather than the number of birds seen. In contrast to the British folk-saying about one swallow doesn't make a Summer, looking at frequencies might mean that one Koel does make a Summer (swallows are around most of the year). My next step was to sort out a concordance between the taxonomies used by: eBird (which follows international rules, and includes some special codes to allow for uncertain identification to species level); and Birdlife Australia (BLA) which is designed for Australia and (in the elements I have used) is restricted to good species. This would allow me to access the data about family membership (eg group all Cuckoos together)...
