Nelson's Sparrow,
subspecies alter, in cattails on 3 August. |

These two Nelson's Sparrows flew into
nets for Yellow Rails and provided a valuable lesson on individual
variation. Closest bird on right is brighter than the left bird, so
one might assume it's the male. However it had a brood patch and is
most likely the female of the pair. The duller bird to the left had
a cloacal protrusion making it male. They were
released unbanded. 6 August. Thanks to Ross Wood for showing us the
sparrows in this and the next photo. |

Michel Gosselin of
the Canadian Museum of Nature commented. These two Nelson's Sparrows
show how much the James Bay population (alter) is
intermediate between the St. Lawrence River population (subvirgatus)
and the Prairie population (nominate nelsoni). The front bird
would go unnoticed among Manitoba Nelson's Sparrows and the same is
true for the back bird among St. Lawrence River birds. |

Dark-eyed Junco was out on the south ridge foraging among
washed up logs, strange habitat for a junco. |

High spring floods
wash woody debris down rivers flowing into James Bay, which later
washes onto the shorelines during storms. |
