I stayed in Amsterdam for 5 days, and for you birders out there this is a very nice thing to do.
Go with the train from Amsterdam central station to Almere Buiten. It takes 30 minutes to get there. On the internet i booked a local bird guide to show me the Oostvaardersplassen. A nature reserve with lots of birds and mammals. You can go by yourself but you need a rental car and the right places to go.
I have booked the birdwatching tour with Flevo Birdwatching (www.birdsnetherlands.nl)
