As mentioned, Mick gave us an idea where we needed to be so settling in it was then a waiting game. Here's an image of Tim, trying his hardest to stay awake and mulling over "have I got the exposure right, am I on the right f stop and is my shutter speed sufficient.
The Grebe did exactly as Mick had predicted and we were rewarded on a couple of occasions when it swam into the little channel where we were lying in wait, giving us both great photo opportunities and also fantastic close up views of the bird.
Other birds seen throughout the morning were 2 Tufted Duck, a Male and Female which kept the Grebe company for a large amount of time during our stay, a Sparrow hawk passed low over the pond and flew off over the road in a Southerly direction, 8 Waxwings were in a tree by the Nucleus building where we had parked and a Ring Necked Parakeet noisily flew over. A Song Thrush could be heard and that was about it. We packed up and left at lunch time as the failing light and the drizzle rendered the session over. If the Grebe stays and an opportunity to return in better conditions arise, then we both said we will re visit. I have placed below links to Mick and Richard's blogs and they are well worth a look.
