Sit while bitten | 9 June 2016 |

This year again there are many fleas in the goose nests. We are studying incubation behaviour in relation to flea infestation. Today we have placed wildlife cameras next to the nests and temperature loggers in the nests. Our expectation is based on a study by Ross Wetherbee in 2014. Geese with heavy infested nests were more restless. The results were close to significance. Now, we are running once more the experiment. In a couple of days, we will kill the insects in half of the observed nests and document the change in incubation behaviour and egg survival. On this picture you can see some clutches full with blood stains, produced by the fleas. In the background Danny Hichcock and Katrin Lang are working. |
