On Thursday, May 2, Christina asked where to find bird breeding dates
for the Pacific Northwest online.

I have three suggestions:

1) Seattle Audubon's Bird Web:

2) The bar graphs of seasonal occurrence that are found in A Birder's
Guide to Washington, Second Edition. The book has been placed online,
including the bar charts. These can be found at :


3) Marv Breece has prepared charts based on the above bar graphs and
broken down by birding groups. You can see and download these at:
