• Filippo RAMPAZZI, Luca PAGANO, 2017 – La nidificazione del biancone Circaetus gallicus nel Cantone Ticino (Svizzera) [Nesting of Short-toed Eagle in the Canton of Ticino (Switzerland)] // Bollettino della Società ticinese di scienze naturali, 105: 77-85. – 
(It) {rough translation}.
The record of successful breeding after the long absence of such data for central southern Switzerland can be considered as an evidence of Short-toed Eagle spread in Switzerland and northern Italy in recent years.
Our sincere thanks to Luca Pagano for kind sharing the paper!
