Nature Notes for the Week May 24-May 30
Spring is well underway, and suddenly Todmorden looks lush
and green as the tree canopy leafs-out. Here are some sights and
sounds that you can expect this week in the Preserve.
Wildflowers

The have faded to deep pink and most of the early woodland spring ephemerals such as
Trout Lily, Bloodroot and Downy Yellow Violets have finished flowering.
But you can see Mayapple flowers this week, and,
if you've never seen the waxy white flower of the Mayapple, it's worth
peering under the wide umbrella-like leaves.
Along the trail-edge, and in sunnier places, look for some of the native wildflowers that
have been re-introduced to Todmorden, especially
,
,
and .
Dame's Rocket, which produces flowers ranging from white to deep pink, is just starting to
flower. This plant has become naturalized in the Preserve, and may be a threat to native wildflowers.
Trees and Shrubs
Most trees are fully leafed out now, and some have produced fruit.
Squirrels are busy eating
Manitoba Maple keys, and recent winds have blown
Elm fruit onto the ground.
The Chokecherry shrubs, one of the more common understorey species at Todmorden,
have nearly finished flowering and the creamy sprays are fading to yellow.
The Hawthorns and invasive Tartarian Honeysuckle
should still be in full bloom.
Frogs and Turtles
The adult
that overwintered in the mud at the bottom of the pond have emerged.
On sunny days you'll likely see them sitting half-submerged at the pond edge.
Listen for the males giving the
characteristic "glug" call which has been likened to the plucking of a loose banjo string.
The
turtles are wary but a quiet approach should reward you with views of them basking
on logs in the pond.
Birds
The tail-end of the warbler migration passed through last week,
and the suite of insectivorous birds feasted on
early caterpillars on the Crack Willows in particular.
Two of our resident insectivorous birds, the Northern Oriole
and the Yellow Warbler started nesting this week.
You should get views of the bright orange male Oriole which has a territory at the pond.
The Yellow Warbler is more often heard than seen, so listen for the male singing
his stuttering song which seems to truncate too quickly.
The noisy and belligerent Red-winged Blackbirds are nesting in
the tall marsh plants fringing the pond and in the oxbow.
Insects
Bumblebees, solitary bees and pollen-eating hoverflies are crowding the
flowering trees and shrubs at present.
And the mosquitoes are back, especially through the swamp section from the Pond
to just north of the stairs, so dress appropriately and bring some repellent.
