## What is Vireo Birdsong Log?

— KEY FEATURES —

• Log Sightings in Seconds — Choose from 25 North American species, add a location, pick a date, and write your own field notes. A confirmation banner appears the moment your sighting is saved.

• Unique Waveform Per Sighting — Each entry generates a distinctive audio waveform visualization, giving every encounter its own visual fingerprint.

• Search & Filter — Find any species instantly by name or family using the live search bar. Tap a family chip to filter the catalog to a single group.

• Rich Sighting Detail — Tap any log entry to see the full species profile: family, habitat, size, key traits, and your personal field notes all in one place.

• Swipe to Delete — Remove any sighting with a quick swipe. Your list stays clean and accurate.
