He really pops out at you as if it were alive, I hate to call animals "it".
All your pictures are great, I use the relatively cheap Tamron 200-500 for birds in my garden
as the Nikons are twice the US price in France where I live (TVA 20% and import taxes). Although I could afford the 200-400 I find it difficult to justify the expense.
Continue the good work. Peter Clark
