Spending some time at a drinking pool can give you all sorts of imagery. All birds will at some point come down to drink and bathe, more so than others. The smaller garden birds such as the finches and tits will come down regularly where there is a constant water source. Here a male Chaffinch is bathing in the shallow water.
