On Friday I spent four hours basking in the heat of the glorious sun staring into blue cloudless skies from the summit of Tower 42 searching in vain for signs of migrations. There was a southwesterly breeze that at times became surprisingly brisk and was the probable reason for our lack of success in seeing anything flying over. Indeed, apart from a couple local Peregrines we saw absolutely zilch.
The whole episode was filmed by a crew from CBBC's Newsround, who were doing a piece for a future show on urban birding. Well, at least they had stunning views across London!
