Is It Small or Just Really Far Away?
An early opening saw a small bat bounce awkwardly away from the near invisible net, a fate not shared by the subsequent thrushes, spadebills and ant wrens that entangled themselves in the black mist like an insect snared in the silk web of a spider. Towards the mornings end, we approached the third net and from a distance we saw what appeared to be a small, white bird, sunbaking in the middle net pocket. Our pace slowed, each step bringing us closer to the bird and with each step the bird grew proportionally greater in size. A White-chested Puffbird (Malacoptila fusca) was found relaxing from its morning activities in the net and was surprisingly much larger than our initial size assessment from a distance of thirty paces. A confused look spread rapidly over our faces in disbelief and scepticism. “But how?” asked the puzzled Australian. After much debate it was decided that the puffbird remained the same size for its entirety and it was in fact our initial distant position from the bird that led to the presumed and ultimately incorrect estimate of its small size.
