On my second ever set of solo circuits out of Biggin I narrowly (very narrowly) missed 2 partridges straddling the 21 centerline on my first takeoff of the day.
Managed to clear them after making the split second decision to continue rather than stop. Came off runway heading a bit but kept a beady eye on the ASI. Couldn't relax for the rest of the session though.
I'd already had to wait for them to move off the taxiway as I was heading for the hold.
The fact it didn't register in my mind that these two daft ground dwelling birds were heading for the runway I was about to use still bugs me to this day...
