Jackdaw 'pellet'

Andy M was intrigued to find what he thought was an owl pellet on his flat roof recently.  Pale in colour, and about 3cm by 1cm, it seemed to contain mostly plant material, such as the husks of grain - not the bones and fur of small animals as might be expected for an owl.
After some investigation, it seems that some corvids, and particularly Jackdaw, also produce 'pellets' and those produced by Jackdaw can be somewhat pale and contain indigestible plant and seed matter. Mystery solved - but sadly no owls!
