[Bluebird-babble] MOBL question

[Robert Wilson]

I have found that when they start a nest and then move to the next box the
cause is most likely lack of food. They will also not start incubating until
there is adequate amount of food in the area of the box. We have had egg in
the nest for 10-14 day before they start incubating.

Thanks Kevin

 

I am just trying to figure out what is going on.  A nest was started in Box
1 and then abandoned before a cup was built.  A nest was started in Box 2
and then abandoned (I thought) before a cup was built.  Then it rained and
the next day the male was displaying to a female (new bird?) at the second
box.  Maybe they stopped building and were waiting for the rain - it has
been very dry and windy all March and April here.

Do male Mountain Bluebirds build a partial nest as part of the courtship
ritual?

Not something I've seen documented anywhere, so I'm guessing the answer is
no.  I do believe that sometimes a pair will start a nest, then abandon it
partway through to build one somewhere else.
