Thread subject: Correlation between young birds and # of eggs laid
Name Date Message
Melanie 05/05/10 10:06 am Is there anything in our ospreypedia about younger birds maybe producing smaller clutches and that larger clutches come with age/maturity?
Marie 05/05/10 01:19 pm From my obs..I would say you are correct but as mature birds age later in their breeding yrs, I find they have smaller clutches too. Maybe just coincidence and the type of birds I monitor.
Pamela 05/07/10 09:29 am According to the 2nd ed. of HANDBOOK OF BIRD BIOLOGY published by Cornell, females laying smaller clutches remains a mystery. However, it may be attributed to younger females nesting later in the season at which time the clutch size declines.
