The chicks are visibly growing every day. This morning we were struck by how much darker they had become as a result of their early growth of feathers. They are also becoming much more noisy, greeting each parent with a clamorous high pitched cheeping. Presented with so many gaping mouths, the parent pops its item of food into any available mouth, and if it is not swallowed immediately, promptly removes it again to give to another chick This may happen several times before it is taken quickly enough to satisfy the parent bird.
