I took my time approaching this pelican - not engaging in eye contact, walking indirectly and generally hoping it thought I was ignoring it - and managed to get within a couple of metres of it. Slowly sat down, and started taking pictures: it seemed quite calm and relaxed. After about 20 minutes I slowly moved away and was taking some shots of a rock pool when a wildlife person arrived. She asked me to stand back because she believed the pelican was sick because of the way it was sitting, and she was going to capture it and take it in for care. She walked directly up to it and the bird was alarmed took flight.

Do any of the pelican experts here know if they sit like this when they are sick? It seemed ok to me: its eyes were bright and it was alert, and it certainly had no trouble flying off when alarmed.
