I can't think of any. The only New Zealand species (of land bird) that seems to meet your requirements is the long-tailed cuckoo (Eudynamis taitensis) which regularly breeds in Stewart Island (47 S), and straggles to the Auckland Islands (51 S), but migrates in our winter time as far north as the Marshall and Caroline Islands (~10 N). All the same, the main wintering range is south of the equator, from Fiji east to Tahiti. The comment of from dmark@acsu.buffalo.edu (David Mark) of 6 Jun 91 11:25:29 GMT: > Next, relatively few of our breedings birds go all the way through to the > temperate zone or antarctic zone.

If one insists that the migrants cross the equator, then even the list of "normal" northern birds wintering south is much reduced. Hamish Spencer (h.spencer@waikato.ac.nz)
