As it gets dark the birds become anxious to break off and fly near by their corresponding lofts. The purpose of the second kit is to add more feather power to the existing first kit. One should be careful because the second kit is not used to venture far from the loft especially in a sky that is getting rapidly darker during the winter season. Few oriental rollers and flying African Owls are also flown in the second kit or soon thereafter to further slow and lower the birds. The tricky part is to steer all the birds to wing off together as well as luring one or two birds from other lofts to come along with a hope of eventual landing and trapping them.
Good birds are always hard to crash.
The strange birds could be flying with your birds long after the sunset before abruptly correcting their course and heading home couple of miles away in total darkness. All the lofts in Egypt are equipped with lights to feed the birds upon landing. The entire loft is also covered by a net system, capable of snatching a bird from the air before it actually touches the loft's roof. The reason is some of these outsider birds lands only for few seconds and off they go again. Many in Egypt don't band their birds, for almost everybody tries to disclaim a crashed bird.
