This is an excellent daily photo journal of the nestling development and some behaviors of the young each day as they progress. Here is the NestWatch page: NestWatch Eastern Bluebird Nestling Development (Daily Nest Photos)
Please remember some good monitoring protocol for the safety of the nestlings and “courtesy” to the parent birds caring for their broods:
- If you keep your own photo journal, try to abstain using flash after the young start to open their eyes on the 7th and 8th day — the flash photography is intrusive on cavity-nesting bird young. I set my small digital camera to the macro setting, which automatically turns off flash and adjusts focus for closeup photography. Long periods of video photography could be intrusive. Attempt to keep videos short-term.
- Please also be quick at the photos using a steady hand and try not to leave the box open too long — this will aid in keeping the smell of the young and any odors from the nest from unpicked up fecal sacs by the parent birds from floating into the air and attracting potential predators towards the young in the nest (snakes!). I try to do all I need to do my checks in 45-60 seconds and close the box securely and leaving quietly. This includes using my auto visor mirror first for inspection, shut the box, ready my digital camera in the macro mode, reopening the box and shooting two photos and then closing the box again SECURELY and carefully and doing my skedaddle from the area so the parents and get back to business of caring for their young and keeping their stress level to a minimum.
- Also remember to abstain from opening your nesting boxes after the 13th day to avoid premature fledging of the nestlings. Do your final check on the 12th or 13th day of the nestling’s age and stop at that point and do your behavior surveillance up to Fledge Day from a distance using binoculars in a comfy chair or bench in the vicinity of the nesting box — not too close because the parent birds won’t like you being there near this time and will delay fledging until they feel comfortable it’s safe for their offspring to make their maiden flights successfully–even wobbly so!–to the safe haven inside a tree and it’s foliage. Yes, even you, the monitor the bluebirds have come to know still don’t want you nearby during the fledging process of their kids. It’s just nature’s way of survival.
- Always keep good monitoring (accurate) records. This will aid you determine their age, of course. Monitor about 2-3 times a week for best accuracy of the goings on inside the nest box and for troubleshooting problems as they arise, BUT AT LEAST ONCE A WEEK MINIMUM…. but not too often (like every day unless the nesting box has problems) so you are not over-managing the birds. After all, they are still wild birds–not your adopted pets.
- Send on your records to your local state bluebird society or ornithology organization like NestWatch or Audubon group! They need the records, even from a back yard nesting box. Find them online and see if there is a County Coordinator near you and contact them and introduce yourself. You may make new friends at these wonderful NABS-affiliated non-profit, all volunteer cavity-nesting bird organizations. You can also participate in Cornell’s NestWatch.
