Animals use the geomagnetic field and astronomical cues to obtain compass information. The magnetic compass is not a uniform mechanism, as several functional modes have been described in different animal groups. The Sun compass requires the internal clock to interpret the position of the Sun. For star compass orientation, night-migrating birds seem to use the star pattern as a whole, without involving the internal clock. Both the astronomical compass mechanisms are based on learning processes to adapt them to the geographic latitude where the animals live and, in long-living animals, to compensate for the seasonal changes. Several mechanisms are used to determine the compass course to a goal. Using information collected during the outward journey is mostly done by path integration: recording the direction with a compass and integrating its twists and turns. Migratory animals have innate programs to guide them to their still unknown goal. Highly mobile animals with large ranges develop a so-called navigational ‘map’, a mental representation of the spatial distribution of navigational factors within their home region and their migration route. The nature of the factors involved is not yet entirely clear; magnetic intensity and inclination are the ones best supported so far.
Pam please tell Donnie these Hansennes do indeed have a lot of class. Large wings like I've never seen like maybe on a duck or owl. They have a lovely prance, and their Roman noses takes the cake. Love it! Keep up the good breeding Donnie.
Dear Don,
Just sending a gift for my appreciation for getting such nice Sion birds from you. When I get some youngsters from them, I will send you some photos. I am still planning on purchase another hen and cock. Have a good breeding season with your birds.
Received birds this morning here in Missouri. They are safe and both beautiful.
Beautiful female pigeon. Lovely mix of colors, fether quality and great posture. I figured her picture wasn't the best pose. The male is impressive and very masculine looking and I'm happy to say they are calm and get along very well together. Thanks again they are gorgeous....
The birds arrived today got them all tucked in the loft. You saved the best for last I think there nice birds ,,only sorry I didn't buy a couple of the other hens. Thanks alot
Hello. I received the birds today they look great. Thank you very much.
The Hen is here! Awesome bird & I can feel the power just holding her. She is very calm pigeon & that is always a plus. Thanks so much!
Hi this is Nate from Wisconsin. I just wanted to let you know the Andalusian cockbird made it here in good shape today. Thanks again!
Hi Don, birds are adapting well. I like their presentaion & calmness. Looks like they will fit in with my birds. I see what you mean about the BB. We'll see how he produces. Might b a genetic thing & go away when crossed with and unrelated hen.
Regards
Jim
