With spring comes flowers in bloom, birds in flight and festivals of all kinds, practically every weekend.

This weekend looks especially busy, with several longtime favorites scheduled.

You can celebrate Petaluma's agricultural heritage with Butter and Egg Days, or the county's rich seafaring history with the Bodega Bay Fisherman's Festival.

And of course, living in Wine County always means plenty of wine tasting events. Two of the best — April in Carneros and Passport to Dry Creek — are both this weekend.

If you're a glutton for fun, it's possible to fit in all four events this weekend, if schedule it right, so here are the details:

<strong>Saturday, April 26 </strong>

<strong>Petaluma Butter and Egg Days.</strong> Running from 8 a.m. to 5 p.m., the 33rd annual community festival features a parade, contests, live music and more.

Quirky and endearing highlights include the cow chip tossing contest at 10 a.m. and the Cutest Li'l Chick Contest for kids at 10:15 a.m.

The parade, which draws thousands every year, starts at noon from Fourth and D Streets and loops through downtown. Free. 762-9348, <a href="http://petalumadowntown.com" target="_blank">petalumadowntown.com</a>.
