Before the test releases, the pigeons underwent further training releases from , , , , , , km X. and , , , , , , , km S; the releases from X and S were alternated according to a random program. During the train- ing releases, performed under both sunny and overcast conditions (8 and 9 releases, respectively), the pigeons were gradually accustomed to flying with equipment similar in size and weight to the coils used in test releases. After the training re- leases, since 21 Al-birds were lost, a further group of 31 pigeons (A2-birds) was added. The A2-birds had similar flight experiences to the Al-birds. This second group of birds was submitted to only two training releases from km X and km S under overcast and sunny conditions, respectively. During these re- leases, the birds wore the same equipment carried by the Al-birds during their last training releases. In training releases, the birds were tossed singly at three minute intervals. B-birds. The second major group of birds consisted of 48 homing pigeons from a loft at Antella (to the south-east of Florence). The birds were all about two years old and had experienced previous releases from all four compass directions, to a maximum range of about 100 kilometers (125 in a few cases). Birds were.
