Frank,
..I have 8 of the 12 months covered with BRB litters in every month from april to november. I plotted them out once several years ago and it was a nice bell curve with the peak in July and August. I have never had a litter of BRBs born in March. I know a lot of breeders from the northern states get their breeding stock cooled earlier than I can here in GA and so they do have litters in March. My Colombian and Argentinian Rainbows seem to depend less on a seasonal cooling period and I have had litters from them in March.

>>Does anyone know if there are known parturitions in every month of the year for Brazilians? I would imagine if Brazilians are aseasonal they would be subjected to different variations of thermo cycling at different times of the year (i.e. Australian winter). Seasonal species like Python m. bivittatus breed at the same time of year all over the world with little variation. Python reticulatus is aseasonal and breeds all different times of the year, documented cases during Australian winter usually off set USA by 6 months, by nature a lot of retic's breeders in New Jersey notice a clustering of breeding behavior during Sept-Dec, most notably in October (mid), but yet people all over are still breeding and getting eggs now in different parts of the USA. If I had bred reticulatus this year my eggs would have normally already hatched in February/March. I was wondering if anyone has such data correlating to Brazilian Rainbow Boas. I am not talking about typical clustering of births, atypical is the information I seek.
