Just had to weigh in on this! A big part of what I look for when seeking parronts for a new bird is compatibility first but just as much I try to match ages or circumstances with extended family when placing a bird. If it's a retired couple such as the 40 year old macaw Mathew that has seizures new parronts , they have worked out story book perfect because I took ages , family circumstances and life style into consideration when matching them up with Mathew.
