Encouraged by the high volume of incoming queries, messages and emails, it seemed to be a good idea and not too late for another blog post to address first aid and emergency care measures, which are likely to be relevant for all native rescue bird species including corvid nestlings and fledglings.
Laniakea came to us as an adult rook in Spring 2017. We did not know for sure how old she was when she arrived. However, it was very obvious to us that Laniakea was already an experienced and mature rook. When we rescued her, it became immediatly apparent that she would never be releasable. This thought was deeply troubling, in particular as it was very likely that Laniakea had a partner, who was waiting for her. Her arrival came with a big shock too, as she had suffered horrendous injuries to her leg, most likely caused by a spring trap. Laniakea had to undergo surgery, but recovered very well from her leg amputation.
It is nesting season and corvid fledglings are about to leave their nests to start the big adventure of life. Corvid fledglings are fully feathered and healthy looking birds, who can perch, stand and hop by themselves. They are already able to fly short distances. Fledglings of many bird species leave the nest at this stage, and for good reasons. If they would remain in the nest, predators could have an easy meal, killing the whole brood at once. Leaving the nest and hiding scattered in trees, in the undergrowth or in bushes, even when not fully developed and not being able to fly properly, is the best way to increase survival chances. It gives fledglings the time and required exercise to improve their flying skills, which often takes less than a week of daily practice, after they have left the nest.
