Without hesitation I can recommend Wildside Birding Tours. I went to Belize with them and had so much fun I went to costa rica with them the following year. Kevin is great at organizing tours and finding local places to stay that are near to the birds, so that as much time as possible is spent birding. Glenn’s ability to locate birds you will have to see to believe! Both are patient and make sure that everyone that wanted to see the bird sees it if at all possible. You won’t find better tour leaders anyplace!
