Thats amazing! Thank you

How do you record altitude? Is it with pressure readings? Amazing data though!

We're not sure sadly. One pair was sitting every day but never saw any young before they abandoned. The other nest was obscured but had plenty of activity for weeks before also seeming to abandon. The other birds on the colony seemed to have a relatively low productivity year so maybe there's a link

Looks like a completely different moth resting like that!
