Key Facts
Blue tits and great tits are among the most studied birds in the world
Nest box provision significantly increases breeding density in suburban areas
Caterpillar availability is critical for successful chick rearing
Climate change is shifting caterpillar peaks relative to tit breeding timing

Welfare Considerations
Tit chick welfare depends on caterpillar availability at the right time, with oak woodland management and reduced pesticide use supporting food chain integrity.
