Here's some info I found with Google:
Description: Jenday Conures look extremly similar to Sun Conures, however, Jendays have almost all green wings (except thier primary flight feathers, which are blue). As you can see from the two pictures above, they have a line of red across the top of their beak (however, some subspecies of Jendays may lack this distinct line). mainly yellow heads, with red/orange tummies.
Talking Ability: Jendays are fair talkers, they can learn a couple words or so (like most other conures), but like most conures, they don't excell in the talking department. But they more than make up for it with their wonderful personalities and beautiful coloring.
Loudness Factor: Jenday conures can be loud at times! However, this is true with almost any conure. Conures usually only get loud however, in the morning and evening for about 10 minutes each time. (Many Conures also will greet their "flock members" when they arrive home from school or work also).
Personality: Jenday conures have wonderful, loving personalities. They make excellent pets (like all conures) as long as you can deal with some noise every now and then. Jenday conures are known to be just as sweet as sun conures, but usually with a slightly cheeper price tag (since they aren't considered by many to be "as pretty" as sun conures). Jenday conures are also often refered to as Jendaya Conures.
