By the year 2002, an estimated 3,000 trumpeters were wintering on the refuge, many having migrated south from their summer range in Canada.

On average, this is the second largest waterfowl species after the trumpeter swan, although male mute swans can easily match or even exceed a male trumpeter in mass. [ 4 ] [ 15 ] Among standard measurements of the mute swan, the wing chord measures 53–62.3 cm (20.9–24.5 in), the tarsus is 10–11.8 cm (3.9–4.6 in) and the bill is 6.9–9 ...
