We discussed asking for photos of breeding evidence, ie. gathering nesting material, courtship, carrying food, feeding young, nestlings, carrying fecal sacs, fledglings etc.  

It's a tricky subject and we don't want to encourage people to disturb nests in order to get a picture, but the information could prove useful if done in a respectful manner.  (That shouldn't be a problem with members on this site.)

I'll look for more input from those involved in the MBBA as to what to look for and exactly what will constitute breeding evidence.  As well as input from members.

I submitted a picture this evening of an example of breeding evidence which would qualify as "probable breeding", I think. While in some cases "nest building" (code NB in the MBBA) is considered "confirmed breeding", I believe it was agreed that cavity excavation in Chickadees was only a probable. This would also be true of Marsh Wrens building nests (they can build several dummies during courtship) and in Red-winged Blackbirds, but MOST birds building nests are considered "Confirmed Breeding".

Peregrine Falcons hatched at The Hopewell Rocks this morning. Video can be seen in the video section. Feel free to email me for more details if needed. The nest can easily be viewed from Big Cove Look-off.

Yep, little white bags of poop and urine, bundled up in a convenient package, ready to drop on your car and in your pool.  Parents take the waste away from the nest to throw predators off.

Hmmm....what are fecal sacks? 

Do some birds carry waste material out of the nest.....?
