I receive 105 active nests, primarily when you’re riding reduced along side surroundings

During the for each and every breeding year i searched for nests intensively around the analysis website. We accompanied brand new fate of any colony until the eggs hatched and/or nest were unsuccessful. Nests was basically went along to between 0900 and you can 1700 hours together with visits endured 2 hundred m from the nest, ranging from 1000 and you can 1700 days. Period of the fresh focal observations ranged from 29 minute to 7 h, together with complete time of observance was 30.5 h. Because the all of our findings varied in length there was indeed circumstances in the that the male is at the new colony all the time, so you’re able to imagine the fresh portion of nest attract we pooled the fresh focal findings from nests that were at the same stage from incubation.

While the males are more likely to desert new colony whenever disrupted at the an initial phase of nesting duration ( Fernandez and you will Reboreda 2000), i monitored all the nests (9 of the eleven instances totaling 34 colony-days) during mid- otherwise 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 vakavat treffisivustot we started the monitoring of the nest three and five days after the laying of the first egg. None of the nests used for monitoring male activity was deserted. We used the decrease in egg temperature to determine when the male left the nest ( Hainsworth et al. 1998, Flint and Grand 1999). We previously estimated egg cooling-rate of Greater Rhea eggs by heating six fresh eggs up to 33°C and then placing them in an environment at a temperature of 25°C, similar to temperatures registered in our study area between 1100 and 1300 hours (the warmest time of the day). We estimated egg cooling-rate by dividing the initial difference in temperature between eggs and the environment by the time elapsed until eggs reached a thermal equilibrium with the environment. The estimated egg cooling-rate for a temperature gradient of 8°C was 0.063 ± 0.01°C min ?1 . We assumed that the male left the nest when the difference in egg temperature was |T(t) ? T(t?1)| > 1°C, where T(t) and T(t?1) are egg temperatures at a time interval of 15 min when data loggers were set at 3.8 min intervals or 18 min when they were set at 6 min intervals. We considered that the male was outside the nest since the time at which the difference between T(t) and T(t?1) was negative until the time it was positive (i.e. the male resumed incubation). Although the sun can heat eggs when the male is absent (particularly at midday), unattended eggs never reached temperatures >30°C (see below). Therefore, it was possible for us to discriminate between an increase in temperature produced by the Sun and one produced by males when they resume incubation.

I along with counted type into the eggs temperatures inside the three fresh nests (nests as opposed to male focus). I made use of nests that were in past times discontinued because experimental nests. For the for each and every nest (clutch products off 16, 21, and you may 23 egg) we repaired one egg having a thermistor into the, to your heart of your own colony similarly that i did with the energetic nests (get a hold of above).
