That would give me the same wing loading on a wing the same size. But if we assume that a 126-lb Parahumanus aves has larger wings than a 40-lb duck don't we get somewhere?

Suppose I take a Dalmatian pelican massing 15 kg, 1.8m long, and with a 3 m wingspan, scale it up by 59%, and take it to na-Barsoom. Its weight goes up by a factor of 1.52, but its wing area goes up by a factor of 2.52.

60 kg is not a big man, and 4.75 m is a huge wingspan. But I can even bring the wingspan down a little and still soar like a pelican. 3.7 m wings on a 60-kg bird on Mars would give the same wing loading as a pelican on Earth.
