Re: [cobirds] Bluebird dearth

[Peter Ruprecht]

Bluebird migration, as visible from my home on the west side of Superior,
was a little different than usual this year.  Normally I'll see small
flocks of Mountain Bluebirds passing by intermittently over a period of
several weeks.  This year, I only saw them for three days (around March
23-26) but there were at least a hundred each day, sometimes in flocks of
40-50.

There have been some good-sized flocks (30+) in other areas of S. Boulder
County since then, but not near my house.  Overall, I'd say the total
number I've seen this year is higher than usual.

[cobirds] Bluebird dearth

['Hugh Kingery' via Colorado Birds]

We have not seen many bluebirds this spring, so I compared this year with the 
three prior years' data. This year we have seen only one or two of either 
species only once in a while. The last 3 years we saw them almost daily 
starting in mid-March.
This drop seems striking, at least along our road and on the trail we walk 
regularly. Have others noticed this pattern?
