One of the nests we knew about has not resulted in success. A female from 2005, who was nesting for the first time, to the best of our knowledge, was seen away from her suspected nest site. She was alone and without chicks. After a second day of this behaviour GBG staff located the nest and found two unhatched eggs. Although there were cold and seemed abandoned they were left untouched for a further 24 hours while intense observations were carried out. The female showed no interest in her eggs and did not go close to the nest site. After some consultation the eggs were recovered in the secure knowledge that they had been abandoned.
The eggs have been examined by John Chitty, the GBG Consultant Vet. Both eggs were fertile and had chicks inside which were about halfway through their development.
The reason for the eggs abandonment is unknown. It may be as simple as the young female does not yet know how long to incubated them for, or some other factor may have caused her to abandon them. This sort of nest behaviour is not uncommon, and in any circumstances all nests do not all successfully produce chicks. That this bird nested is a relevant achievement, and she has many years in front of her to find success. She is likely to be in breeding condition for the next 10 years or so.
The other chicks are doing well, and there are still other nests from which we are waiting results.
