March 1   En route home this morning we stopped at Tualatin River NWR.

At the refuge the duck numbers were reduced from last week and there were no cormorants or Cackling Geese.  There were many more Tree Swallows and I managed to pick out one Violet-green from the swarm of 200 or more.  It was my 100th species of the year. Red-winged Blackbirds were singing about their territorial claims in various parts of the marsh.

Far off across the marsh two Great Blue Herons had found a good use for the hunters’  blind.  They made it a hunters’ landing:two-gbh

An afternoon walk at Rotary Park found few birds but many prone or horizontal trees as erosion and winter storms thin the forest and leave holes in the canopy.

Some larger trees took out smaller ones as they fell.  Most tore off neighbor’s limbs.  Rootballs tore from the earth.  One large alder fell across a pool.  One aged maple lost most of its living trunk, another fell over completely and will die.img_8805img_8808Here a trail ends at a fallen maple carcass:trail-endsimg_8812img_8813Large maple with twin trunks undercut, felled by erosion from nearby street.  Leaves large opening in the canopy:mapl-undercut

At home War-war came back into the garden for the first time I’ve noticed in some days.
