Investigation of demographic patterns of Psittacula krameri

My STSM was great! I have spent six weeks at the Max Planck Institute for Ornithology in Seewiesen, Germany, under the supervision of Dr. Julia Schroeder - leader of Working Group 3. The objectives of my short mission were to review demographic parameters regarding data type and quality and perform a data analysis across populations, geographic locations and land use. This review was specifically intended for Rose-ringed Parakeet populations across Europe, which is known to be the most invasive parrot species for the continent.

During the STSM, I have collated data parameters of databases from ParrotNet members, a total of 54 demography-orientated programs. I have reviewed spatial and temporal data from published papers and grey literature. Furthermore, I have checked online resources for presence and abundance of Rose-ringed Parakeets across Europe. For countries where no data was available e.g. Romania, Finland, I have approached birdwatching organizations and even my personal friends.

My final report contains lines for future research directions and ways to fill in data gaps that currently prevent us from having a complete overview on what factors are needed for Rose-ringed Parakeet populations to grow and spread. The ParrotNet Group is still in its early stage and I believe my contribution will increase efficiency of this ECOST Action, by offering an image on what kind of demographical data is available for invasive parakeets in Europe and what should be our future aims. The time spent at the host institution - Max Planck Institute for Ornithology has greatly improved my knowledge on invasive species, approach to data collation and, overall, my vision on how short-term research should be pursued. During my staying, I was actively involved in the activities of my host's group: scientific writing sessions, talks, etc. I am grateful to the Action Chair Committee and to my host for the chance to hold one of the first STSM's. I encourage all young researchers having an interest for alien species to pursue a short mission within the ParrotNet Group.
