I recently saw a Cornell Lab video of a Kestrel box where the substrate at the bottom of the box was some sort of pebble mix instead of say wood shavings. Is this a better/worse substrate for the eggs or does it work against European Starlings better?
Hi - I really enjoyed reading the recent paper about the Kestrel Cam! I hope that in spite of there being no little family this year there will be another Kestrel Cam season in 2019. Can you still use our observations?
