After parking the car then taking a short walk to the ''going to roost'' view spot in Herts. I scanned the trees for perhaps 20 mins (to no avail), thus decided to turnaround and retrace my steps, in doing so...I espied an odd looking protrusion atop lofty pine, some several rows back behind a matrix of twigs. It was a straight choice...camera or bins? I opted to shoot first! a quick manual focus ''Christ it is!'' followed by the shutter release, and this grab was taken from just a short film clip. Dropped camera and picked up bins...it had vanished just like ''the airline'' :-O
On a more serious note the roost numbers appeared to be somewhat reduced since the reported 60+ of last week, and the 20+earlier this week! I could only raise c6 this evening! Am hoping that my endeavours today were just the ''tip of the iceberg'' and that the core numbers were still present, albeit hidden from view. I don't know if Hawfinches alternate their roost sites, or disperse into smaller roosts elsewhere, time might tell hopefully.
Cheers
