I had just a short time at the end of a business trip, but wanted to fit in some birding.; I was able to arrange a trip with Ben Gaxiola of Birding Holland. Visiting a number of sites in North Holland in the afternoon, followed by others near Rotterdam the next morning, we were able to find over 100 species even in mid-April, including specialties like Bittern and Grasshopper Warbler!
