Wow, top drawer - how long were you at the sighting for?
We spent around an hour with the kittens in nice late afternoon light, we were the second on the sighting and by the end
it was like Red Indians around a covered wagon, with many dozens of long lenses firing away in succession every time this pair made a move! Nothing in the mara (especially) @ migration time remains secret for long.
Regarding the den site image, after this shot, we went back after a few days to check on the pair to find that a vehicle had got far too close by driving right over the den completely collapsing it. Fortunately the kittens were not in at the time.
