Abstract

In order to find possible safe havens and alternative stopover sites for Red Knots migrating along the East Asian-Australasian Flyway, 30 Red Knots were caught and outfitted with satellite tags. The focus of this research was: the spatial distribution of the Red knots on the northern shores of Roebuck Bay and measuring the possible effects which the satellite tags could impose on the birds. A control group of 24 colour banded Red Knots was used to see whether there were behavioural differences between the birds carrying a satellite tag and the birds outfitted with colour bands. A lager group of previously colour banded Red Knots gave insights in the preferences of certain beaches over time. Both the colour banded control group as the satellite tagged birds were followed over a period of one month prior to migration. The east and middle of Roebuck Bay, was mostly frequented by colour banded birds while most satellite birds visited the west of the bay. It proved to be possible for Red Knots to complete their 6000 km migration from Roebuck Bay to Bohai Bay, China, while carrying a satellite tag. Once firmly attached to the birds, the satellite tags worked beautifully and showed stopover over sites previously unknown to science.
