|Description of video-recording.|
|11 May||15 sec||May 11, for Common Swifts the third night after they came back from South-Africa. Clearly you see that the present Common Swift, when his/her partner comes in, he goes in defence. After the duet call booth go sit on the nesting-place and started to clean each other. That cleaning, with the typical noises, can do them endless.|
|22 May||20 sec||May 22 the third egg is there. In the evening, when the partner comes in, you can see all three eggs.|
|27 May||8 sec||May 27, the sun is shining all day, with east wind it will be 32 grades outside. Into the nest box it is so warm that the adult Common Swift regular stops breeding.|
|28 May||14 sec||At this fragment we see, while a Common Swift is breeding on the nesting-place, the other Common Swift takes care of his feather tail.|
|8 June||14 sec||The first egg is coming out. Clearly you can see the Common Swift that comes in, donít have any feed.|
|10 June||15 sec||June the 10th the third egg is coming out. We see at the video that two young Common Swifts are feeding by an adult Common Swift.|
|19 June||11 sec||June 19 is a warm day, 31 grades Celsius. We see a Common Swift has feed a young Common Swift (11 days old) and after that, he clears up the excrements. While he/she is working on it we see creep a Common Swift louse fly (Crataerina pallida) about the bird.|
|7 July||12 sec||A Common Swift comes in for feeding. In confusion that is caused by, young Common Swifts canít find the Common Swift that was coming in. You can clearly see the adult bird has feed with him. Look at the reaction rate of the young Common Swifts when the adult bird comes in.|
|15 July||34 sec||On the movie we see 2 young Common Swifts of 37 days old who are doing flying practise. One of them has pushed up himself against the vertical wall and beats his wings in a quick-tempered.|
|15 July||24 sec||Still more flying practice. A young Common Swift has clung his claws to the vertical wall of the nest box. He starts practices with his wings and, at the same time, he goes backwards like he flies upside down. Also attend the power he must have to come back in the normal position.|
|16 July||14 sec||3 young Common Swifts. Next day one of them leaves the nest box.|
|17 July||32 sec||At 22:10 the first young Common Swift, 39 days old, leaves the nest box. At the left side in the corner and at the nesting-place are the other two. Clearly you can see the restless and desperation of the young Common Swifts, shall I go or shall I still not. The whole evening outside a group of 20 Common Swifts flies around. It may be possible you think that they encouraged the young Common Swifts to connect themselves with them.|
