Hollow dimension data has been collected from most of the hollows as has fledging success rate, fledging sex ratio (0.7 females to 1male) and timing of fledging. Highlights of last season’s research includeĪ further 25 nest hollows were identified across much of the Gang-gang's range. Gang-gang hollow checking is increasing as we approach breeding season and we ask that you keep posting sightings of where you observe Gangs-gangs looking into hollows, but particularly in remote or rural areas away from Canberra. We have 5 years of good data from Canberra but would like to compare what we are finding here with that elsewhere. We continue to learn much about Gang-gang nesting ecology and behaviour. In total we have now identified 60 nests (52 in Canberra, 2 in Campbelltown, 2 in Wombat State forest (Vic) and one near or in Moruya, Cooma, Tumbarumba and East Melbourne). Thanks to the many of you that contributed to the Gang-gang nest hollow project. Genetic information extracted from Gang-gang feathers may also provide insights into their habitat use, mating systems and conservation status across their range. Knowing the population size of a species, and monitoring changes to this over time, can directly inform planning and implementing conservation actions. They provide insights into the biology and ecology of birds that are otherwise challenging to sample, and in a way that is not intrusive.īy learning about the genetic variability of Gang-gangs, we can estimate their ‘effective population size’. This project aims to better understand the population genetics of Gang-gang Cockatoos iacross their range through feather collection.įeathers contain genetic information unique to an individual.
