I receive 105 energetic nests, mainly when you are operating slow over the landscape
Throughout the per reproduction seasons we searched for nests intensively all-over the study site. I implemented the fate each and every colony through to the eggs hatched or perhaps the nest hit a brick wall. Nests was basically visited anywhere between 0900 and you may 1700 circumstances together with check outs endured 2 hundred m away from the nest, anywhere between 1000 and you may 1700 era. Duration of the fresh focal observations varied away from 29 minute to help you 7 h, while the total lifetime of observance is actually 31.5 h. Given that our very own findings ranged long so there have been instances inside the that your men was at the newest nest throughout the day, in order to estimate the portion of colony notice i pooled brand new focal findings out-of nests that have been in one stage from incubation.
Since guys are more inclined to wasteland the nest when interrupted in the an early stage of nesting stage ( Fernandez and you will Reboreda 2000), we tracked a good many nests (nine of the eleven instances totaling 34 nest-days) through the mid- or later incubation
The thermistor of the temperature logger was introduced in a fresh natural orphan egg (unattended eggs laid far from active nests; Navarro et al. 1998) through a small hole in the equatorial plane and fixed to the eggshell with epoxy adhesive. The egg was attached to the center of the nest and the data logger was hidden under the nest. The data logger automatically recorded the temperature at 3.8 or 6 min intervals during four or six days, respectively. We monitored egg temperatures in those 11 nests totaling 40 nest-days. In the other two cases we started the monitoring of the nest three and five days after the laying of the first egg.
