Grebe and rather large offspring on the park lake

My tea time bike ride to East park yielded several shot of this Grebe, and then rather to my surprise up popped it's offspring, there was just the one, but I shall certainly keep a look out over the next few days, as of course there could well be more, and with luck they won't be over 100 yards away as these two were.
Grebe are  not very frequent visited to this park, which is smack in the middle of the city, but will certainly find it attractive as it is well stocked with fish and Anglers on the banks are far more numerous than the Grebe ever are!
There's an additional image of the parent bird too.
