Do I need waterproof binoculars for birdwatching?

Yes, waterproof and fog-proof binoculars are strongly recommended. Morning dew, unexpected rain, and humidity changes are common in the field, and moisture inside the optics can permanently damage the glass coatings. Most quality birding binoculars are nitrogen-purged and O-ring sealed.

Are roof prism or Porro prism binoculars better for birding?

Roof prism binoculars are the standard choice for birdwatching because they are more compact, lighter, and easier to hold during long sessions. While Porro prism models can offer slightly better depth perception, roof prism designs dominate the modern birding market due to their ergonomic advantages.
