Are Dusky Woodswallows migrants

[martin butterfield <>]

Following the recent discussion on this topic I have ferretted in the GBS database to see whether value can be added to the debate.  As the result:

• is too long for Gang-gang;
• but doesn't cover all the bases that need a lid for CBN; and
• some folk may not like an attachment

 I have put the outcome at http://franmart.blogspot.com/2009/04/are-dusky-woodswallows-migrants.html.
