Introduction

The data

This overview is generated using the data from the AWSG, updated on 02 August, 2023. For species where sufficient data is available, minimal age overviews and variations in juvenile percentages over the years are being calculated and provided. The data does not include ABBBS recoveries and leg-flag sightings.

Some noteworthy data characteristics:

  • it includes all birds originally banded as adults, immatures or juveniles by the VWSG in South Eastern Australia and notably Victoria (for approximate area covered by these activities see map below).

  • it contains data where a year (season) runs from August 1- July 31 the next year.

  • it presents conservative age overviews (e.g. a bird aged 2+ upon banding was assumed to be 2 years of age).

  • the data has been rather conservatively filtered for obvious errors in observations.

Species overviews

The age overview and juvenile percentages are shown for each species in alphabetical order. For each species a separate html file is generated.
