Chain Migration in Swifts

I look forward to early-May every year and there's a massive woop of delight when I see my first SWIFT of the year. Utterly amazing bird !

I'm from Morocco (Casablanca to be exact)..and swifts are one of my favorite birds there used to be lots of them here especially during the summer and they live under window shutters (the exterior ones not sure if that's what they are called) they are lively in summer I remember spending hours watching them when I was young. Unfortunately I noticed there numbers declining over the years and just assumed they changed habitats. Didn't know it was a global decline.. Anyway this was an informative video thanks

Been watching loads of Swifts flying in pairs over Brighton tonight. Just wonderful!

I love trying to photograph Swifts. It helps to know their habits so thanks for sharing essential knowledge!👍😀

Thank you, it’s amazing how they survive on the wing, amazing and beautiful ❤️👌

For the last 5 years they were on Warsaw Poland at 10th of may. This year it's a 3rd of may. Always happy to hear them.

Please keep this kind of thing coming 🤩 thank you!

Thank you for this highly informative video about a fascinating animal.

The study done on the Cambridge Swifts with geotrackers just a few years or so ago, showed the male birds stayed mainly in the Congo basin and the females went much further south and east. Does this new study contradict that I wonder? Would be great to see the whole of the study, fascinating stuff. Thank you BTO

My biggest concern for all migrating birds, are wind farms & although certain birds fly at higher altitudes, it's often weather department. Let's not forget the Needle Tailed Swift that meet with it's demise, due to a wind turbine on the isle of Harris. ☹️

I'm moored with my narrowboat at Chirk Aqueduct in the UK. It's 18 July and plenty of Swifts flying around in and out of the arches

This my Spirit Bird when I first saw theses birds in flight I feel in love with them all ...I praised God The Most High The Farther for them all and there Mystical way of fight . The only bird in the world 🌎 that's stays In flight when they sleep and for 10 months can stay in full flight mode....there is no bird that can do this ....there is nothing mankind has invented that can do this...I always look for them In Summer time when they fly over my block 🚫 of flats and houses 🏘 amazing grace and speed and are a collective family 👪...They stick together ❤ always.

Last year in the nest I have on my home, im pretty sure the youngsters left a couple of weeks after the parents had left. End of August

Swifts seen May 12th in Sanquhar, southern Scotland this year. They nest in uninhabited buildings off the High Street. Smaller numbers than a decade ago. I had no idea they were in the UK for such a short time.each year.

weve got in the box this year 2022

In Perthshire there has never been so many,

My Swifts have left already. I cant even see any in the sky. Good breeding season

interesting, thank you.

My swifts arrive 5th may and leave 13th Aug but this year arrive 29th April and left 18th sept lincs uk

To me, Summer in the UK is heralded by the sight of the first Swift in the air or hearing the familiar chirrup.
