Lapland Longspur Wintering Range
- Although this species does straggler into Arizona, the main aspect of its
range is in a broad arc /band across the US which ranges to the Canadian
border in the west ,dips within the central area to the Gulf Coast, and
approaches the southern tip of Ontario.
The maps suggest that these are found throughout the Rocky Mountains. This
seems unlikely. Perhaps they occur within some of the valleys. Perhaps the
key factor may the typical amount of snow cover and the typical seasonal
temperatures, with them moving farther south during intervals and years such
as this one.
Several years ago, I saw large numbers of Lapland's in mid-winter at the
Poplar Creek Hydro Reservoir near Coronach. And they are reported at
Bromhead and have been seen at Regina during CBC's. I believe they are more
regular in winter in the southwest of the Province which typically features
milder temps and less snow cover.

Longspurs where there was little if no snow cover. Where it was easy for
LALO to forage and find seeds would be where we found flocks of them. Air
temperature did not matter. Or if it did, it would be a question of LALO
more likely staying together as the temperature dropped - a not uncommon
occurrence with other birds and animals as the weather gets more severe.
This is not to say that milder temperatures - chinooks and the like, do not
play their part. But that would be because there would be more snow melt as
the temperature rises exposuring seed and soil.
