The following ideas are just a few of the things that will help make the most of an exciting trip to watch birds in Costa Rica:
Quality Binocular: Humid and rainy conditions are common in Costa Rica, even during the dry season. Be prepared to see more birds by using good binos that are both waterproof and fogproof. Use binos that are 7 or 8 x 42 instead of 10 x 25 because they let in more light; essential for the dim conditions inside humid forests.
A field guide: The Garrigues and Dean guide is the book to get but if you would rather have a digital field guide that allows you to take and email notes, hear birds while looking at photos of them, and other features, bring the Costa Rica Birds Field Guide app.
A hat: Whether wide-brimmed or a baseball cap, this essential accessory will keep the sun and glare out of your eyes and provide some protection from the sun.
A small umbrella: An easy and lightweight means of being ready for rain!
Lightweight, long pants and long-sleeved shirts: Quick dry, outdoor or expedition clothing are excellent choices for birding in the tropical habitats of Costa Rica.
Ziplock bags: These are for keeping your devices and stuff dry!
Water bottle: Bring your favorite water bottle or camel back water carrying device to stay hydrated in hot weather.
Energy bars: These are easy to bring and always come in handy when you need a quick bite to eat during the early morning hours.
