I had a feeling of excitement and being somewhat privileged to observe wild vultures taking part in their first migration, en route to Africa. We were able to visit a site where our young Griffon Vultures had made an overnight stop and were in the process of getting ready for the next stage in their long journey out of Europe. The small group we came across had a companion in the form of a young Egyptian Vulture and the size difference between the two species was highly apparent. On many occasions when I have flown in jet airliners, I have noticed the wing flaps partially down on take-off, a standard requirement in order to obtain 'lift' straightaway. Watching these Griffons make their short running 'taxi', I noticed on the left bird below, how the wings are angled steeply down. The airflow hitting the wings is forced downward, creating an opposite force to lift the wings. This gives the bird sufficient height to clear the ground and enable full wingbeats, lifting the birds higher off the ground. Once a reasonable height is achieved, the job of finding air currents with a good 'lift' begins and the wings take on a fully extended shape. Even the wing extensions or 'fingers' can raise or lower, to make fine adjustments. Soaring in a circular manner, it was surprising how quickly height was being achieved and it wasn't long before these majestic vultures were on their way. Who says vultures cant be 'cute'! Meanwhile, back in Sagres this afternoon. I refound the Bee-eater close to Pinhal Ceramica, assuming it is the same individual. Another species often local to Sagres is the Jackdaw, an uncommon crow family member and a small flock passed me in the same location. You are more likely to see Chough here than Jackdaw!
