Entry of a Swift with nesting materiaal, normal speed and slowed down. A Swift enters and starts to brood. A Swift with nesting material entered, adds the material to the nest and takes over brooding. A combination of two clips of more entries with nesting material. The second entry was 20 minutes after the first. |
|
A Swift leaves the nest box and allows some following. |
|
A first glimpse of the first hatched young Swift! |

Feeding the young Swifts. Bangers around our house. More Swifts around our house. One last video of bangers around our house. |
|
The three young are fed. |
|
It's getting hard to cover the rappidly growing young Swifts! Feeding the young. |
|
The three young are fed and the nest is kept clean... |
|

Feeding the young. |
|
A chaotic feeding session. The young are really starting to look like Swifts! :) |
|
The second parent of three young Swifts in on of my nest boxes returns to feed the young. |
|
The young Common Swifts out of the nest on a very warm (30 degrees Centigrade) day. A parent comes in to feed. The 2nd box is still empty. One of the young Swifts practises flight by flapping it's wings and doing push-ups. A parent enters to feed and cleans the nest by eating the droppings. |
|
One of the young Common Swifts in one of my nest boxes does a little moonwalk at 0:46. A bit later, a parent comes in to feed the young. |
|
One of the Swift chicks practises. |
|
Just a quiet view of the young Swifts. Note the white edges of the wing feathers. Those are some of the details I have to watch for now to tell the young
apart from the adults when I can't see the pale face for example. |
|
The second parent of the three young in one of my nest boxes comes home late in the evening (half past ten) with a throat full of food, very clearly
visible at 0:07. |
 Two of three young Swifts practise flight. A chaotic feeding session. Recorded just after the practise of two of the young (see above). |
|
One of the young Swifts practises. Everywhere. Even on top of it's siblings... Pictures taken from across the street: 
|
|
A 'feeding session' without a parent? The young respond to something in the way they do when a parent enters, but that's not the case. Perhaps one of the
young saw a parent approach that didn't enter in the end? Both parents come in to feed the young. Recorded just after the video above. |
|
A frantic practise session! Note how the young actually jumps pushing itself up on it's wing tips! |
|
The last two of three young Swifts in my nest box fledge in the morning (10:30)... The parents in the evening. This video shows a clear bolus of insect food in the throat of one of them and how it's eaten several minutes after the bird entered. |
|
The parents of three fledged young Swifts enter my nest box at around ten in the evening. |
