I am a novice birder and did a private 1/2 day tour with Vicente and it was really fantastic. He picked me up at my hotel and we were off. We saw 45 species that morning/early afternoon, including a couple of rare species (e.g. the marble duck). Vicente is incredibly knowledgable and personablel. I learned a lot from him. He knows the area and the birds so well – and can find and spot birds that I never would have found on my own. I was in Spain for 10 days and this was my favorite activity! Highly recommend!
