Piles of rotting pigeon corpses have been discovered at Gowling WLG's London office, with observers blaming a quirk in the building's design.
A cavity behind the facade of the firm's swanky riverside premises functions as a "pigeon death trap", said a source, who witnessed the death of a pigeon this week after it "entered the glass void and was unable to find its route to freedom".
The "appalled" twitcher said they tracked the unfortunate bird to its final resting place, and was "horrified to discover that there were tens of bodies of deceased pigeons steadily decomposing in the bottom of the void".
Despite making calls to the building's front desk, the landlord, and the law firm's reception, the concerned ornithologist said the distressed creature was "left to expire".
On Thursday morning a "sheepish individual with a bin bag" was spotted retrieving some of the rotting carcasses from the avian death trough, which is apparently located next to the kitchen facilities for Gowling's client hospitality floor.
Although the volume of bodies indicated that it was a "well-known and ongoing issue with the building", bird-proofing "is clearly not considered a priority" by the landlord, said a source.
However, WLG Gowling is on the case. A spokesperson said, "Now we are aware of this incident we have escalated it to our landlord to act as we are concerned about the welfare of the birds".
"As tenants we are unfortunately not in a position to alter the external fabric of the building, but we will be encouraging them to address this on behalf of all the tenants of the building."
