There is zero competition for cavaties and I beleive the BBWD will produce multiple clutches if possible.
Last year, I saw BBWD clutches after Helene that had just hatched and a clutch that was not large enough to fly yet in mid November.
Interesting read and study Dylan Balkner did on BBWD's that might interest you.
