First of all I know nothing about Ct; however, I do have good knowledge of pears in general. Addressing the questions and issues raised above:
Are there any Pear trees that are late droppers? Do pears drop earlier than apples?: I grow pears that drop from Mid-Summer through December.
Also, is there a Pear tree that is like the DR Liberty Apple as far as being DR?: In general, pears are much easier to grow than apples. To start with, they are not affected by CAR. Fireblight is a big problem for pears, but there are several good varieties which are nearly immune to it, and a few others that show minor infections but still bear good crops and remain healthy. Moonglow is probably the most bulletproof pear I have ever seen and what I would compare to Liberty in Apples. Kieffer would be close to that but can show very minor signs of FB in some growing areas. There are many other great choices in pears. As Mortenson pointed out - there are some fake Kieffers out there. Some of those are not bad pears, but others are problematic. One well known variety that I would avoid is Bartlett. It is highly prone to FB, and can get to looking really bad in a severe strike. However, it generally doesn't kill an old tree, and they will generally still make quite a bit of fruit despite the disease. Look at my fruit tree post for information on other varieties I've had success with.
What rootstock would any of the pear growers recommend for Wildlife purposes only in Ct . I don't know about Ct. but I prefer OHxF 97, which makes close to a full sized tree, and OHxF 87 which makes a semi dwarf. Both of these are widely planted and have a good track record.
PS: Blue Hill has some pear varieties that I don't have, and I'm going to get some of those. I can tell from talking to Ryan on the phone that he really knows his stuff. For someone in the north, he should be a great go-to guy for advice on growing zones, etc....
