Jackson Bottom birds: April 10-16, 2010

Wow! a lot of trees leafed out over the weekend! Alders and willows are fully leafed out and the maples have bloomed. Ash, cottonwoods, and hawthorn have lots of leaves. The shrubs are full, too, with osoberry, wild rose, and snowberry making up the bulk of the riparian understory.

By mid-week the waters from last week's rains subsided substantially, though some riverside trails remained flooded.

New migrants this week included ORANGE-CROWNED WARBLERS (finally!) on April 12 and BLACK-THROATED GRAY WARBLER and an early PACIFIC-SLOPE FLYCATCHER on April 13. A VIRGINIA RAIL called on April 15, quite late for our first sighting of the season.

I located another BUSHTIT nest under construction during the week.

The GREAT HORNED OWL chick fledged last week and is no longer on its nest.

A stunning WHITE-THROATED SPARROW is hanging out at the front feeders. The white head stripes and throat really contrast with the dark sooty gray breast.

In mammal news, a MINK was spotted this week, verifying an anonymous report on the sightings board from last week.
