Uccle’s two falcons have hatched!
The hatching of the 2 eggs of the Uccle Peregrine pair was expected last Wednesday after 32 days of incubation. The first chirps were heard on Thursday. Hatching was therefore imminent but... we had to wait until Sunday morning to see the first chicks emerge from the shell on its own! The second falcon chick broke free from its shell this morning, shortly before dawn.
See them in real life!!
This year we are once again offering you the possibility of observing by screen (GSM, tablet, PC, TV) 3 families of Peregrine falcons via camera/server/encoder/streamer, systems installed by real specialists, there in the tower of a cathedral, there behind the clock of a church, there at the top of the belfry of the historic building of a prestigious university! Each time it is a technical challenge and... a significant budget. Because obviously, the installations in question have nothing comparable to the webcam of a computer which allows you to chat with Aunt Christine seated in her armchair at the other end of the street! A huge thanks therefore to the institutions which welcome us, and which finance all the expenses linked to the Falcons for All program!
Eggs are chirping in Uccle!
The first time a pair of Peregrines were nesting at the Saint Job church in Uccle dates from spring 2015. The male is ringed! Deciphering the code on his ring allows us to know that he was born in April 2012 in the Saint Rombaut cathedral in Mechelen. The distance between Mechelen and Uccle is 28 km.
They almost disappeared, the sequel
From 1955, many birds were found dead in agricultural areas of the British Isles. The relationship was then quickly established with the newcomers among persistent organic pollutants: aldrin and dieldrin belonging to the sad family of cycloidienes. These substances are powerful insecticides which are used in particular in the coating of seeds in order to protect them – preventively – from insects. The problem is that it turns out that in high doses, these products are... fatal, including for humans. This was observed on workers or farmers who had to handle large quantities of the product.
They almost disappeared!
The recent history of Peregrine Falcons is particularly eventful. How can we imagine that this bird, which today nests in the corners of Brussels, disappeared from Belgium between the end of the 1960s and 1994? What exactly happened?
A new spring of observation
A new spring but not just any spring! Exactly 20 years ago, a pair of Peregrine falcons settled in the center of Brussels, at the top of the north tower of the Cathedral of Saints Michael and Gudule.


A new season of observation coming soon
