eBird turns ordinary birdwatching checklists into a global record of species, place and time that scientists can use to track change.

Why it matters

The idea in context

Citizen science often begins with attention rather than a laboratory. A birdwatcher notes what was seen, where and when; multiplied across years and continents, those notes reveal migration, decline, recovery and shifting ranges. A small act of noticing becomes evidence at planetary scale.

Aynı kart, başka bir dilde.

eBird'de bir gözlemci gördüğü kuşu, yeri ve zamanı kaydeder; bu küçük notlar birleşince göçü, azalmayı ve toparlanmayı izleyen bilimsel veriye dönüşür.

Yurttaş bilimi bazen dürbünle başlar. Parkta, kıyıda ya da tarlada tutulan kısa bir liste tek başına mütevazıdır; milyonlarca liste bir araya geldiğinde türlerin nerede çoğaldığını, nereden çekildiğini ve mevsimlerin nasıl kaydığını gösterir. Kişisel dikkat, düzenli kayda dönüşünce doğanın büyük hareketleri okunabilir hâle gelir.
