Blooming Flowers, Insects and Birds!

Spring Ephemerals have begun blooming! Bloodroot flowers are opening, while the leaves are still curved around the stem. When the leaves open, they remind me of large, green, butterflies!

Hepatica (sp).The 3-lobed leaves will not emerge until the flowers have fallen. The leaf shape is important in identifying the exact species of hepatica.

Pussy Willow (sp) catkins are now flowering!

The willow flowers are attracting many insects including a Cellophane bee which is covered in yellow pollen. Catkins are important because they appear very early in the year, providing a critical first source of nectar and pollen for newly emerged insect pollinators. This early supply helps to bridge the food gap before other plants begin to bloom!

Insects are attracted to the Willow Catkins for food. The insects then become food for birds such as this Ruby-crowned Kinglet. The Kinglet secured a personal feast by chasing away other approaching kinglets.

More and more insects are being spotted on the sunnier, warmer days. I watched 6 Green Darner dragonflies rapidly skimming along the meadow. They kept crossing the path beside me. I had some good looks, but not one of them landed for a photo. While trying to keep my eye on the dragonflies, I started noticing other insects in the meadow, including a couple of Virginia Ctenucha moth caterpillars.

Northern Azure! First of year!

Hundreds of tiny ants emerged from the ground. They will make excellent food for birds such as the Northern Flicker!

Mallards are not known for "playing nice" when it comes to mating season.

 Drink your Teaaa!

The classic Eastern Towhee song, given by males, sounds like a loud "drink-your-tea"! A pair of Towhees have spent the past few days in or near our yard. This bird is typically found in the undergrowth, so we were delighted to have it break out in song while in a clear location! They are most often found scratching in leaves on the ground, making a loud rustling sound.

A Ruby-crowned Kinglet was eyeing up possibilities for her next snack! Many flies were at the tree, drinking sap dripping from holes made by a Yellow-bellied Sapsucker. Ruby-crowned Kinglets are one of the smallest song birds in North America. 

Yellow-bellied Sapsuckers have been reported drilling sap wells in more than 1,000 species of trees and woody plants, though they have a strong preference for birches and maples because of the higher sugar content. The sap attracts insects, an important food source for the species.

Butterflies, such as this Eastern Comma, and many other insects are currently benefiting from sap dripping from trees. The bark is dark because it is covered in dripping sap.

Sarnia Bay has been a popular resting spot during migration this week. Recent rainfall and subsequent run off from farm fields makes it difficult for birds to forage for food in the cloudy waters of Lake Huron. A few of the species found in the clearer waters at the Bay are below:

Male Bufflehead sporting his iridescent colours in the sunlight.

As many as 9 Common Loons have been reported at Sarnia Bay. I managed to locate 5 of them.

Immature Common Loon, with juvenile colours. (From a distance I had originally hoped that this was a different loon species.)

Double-crested Cormorant: The "stringy, feathery double crests" are visible on males only during breeding season.

Horned Grebe, moulting into spring breeding colours.

Red-breasted Merganser, male. This species was the dominant species at the Sarnia Bay with well over 500 individuals being seen.

Female, or immature Long-tailed Duck

 More Spring Things!

Eastern Bluebirds were checking out a nesting location! The male Eastern Bluebird displays at his nest cavity to attract a female. He brings nest material to the hole, goes in and out, and waves his wings while perched above it. That is pretty much his contribution to nest building; only the female builds the nest and incubates the eggs.

A very vocal Red-bellied Woodpecker was drumming up attention at this nesting cavity. Perhaps he was still trying to attract a mate? When exiting the cavity, he cautiously poked out of the hole, making sure the coast was clear of potential predators.

Red-winged Blackbirds continue to make announcements to anyone who will listen!

On a very windy morning, some Turkey Vultures chose to roost in a tree rather than tackle the windy conditions. Turkey Vultures use their sense of smell to locate carrion. The part of the brain responsible for processing smells is particularly large, when compared to other birds. It can even detect dead animals below a forest canopy!

Grabbing a snack! A Black-capped Chickadee enjoyed the Staghorn Sumac fruit.

Brown-headed Cowbirds are native to North America but are considered by many to be a nuisance bird. They have been implicated in the decline of several endangered species, including the Kirtland's Warbler. Female cowbirds make no nest. Instead, they lay their eggs in the nests of other bird species who then raise the young cowbirds, often to the detriment of their natural offspring.

Song Sparrow, taking a break from singing!

Female Bufflehead: I had been watching this bird paddling, about 50 feet in front of me. She suddenly took flight and landed directly across from where I was standing! She must have wanted her picture taken!

It's nesting time for Eastern Screech Owls. Males choose a roosting location which gives them a view of the nesting cavity where the female sits.

 Warm Temperatures, Active Insects!

A truly unexpected find at this time of year was a Bronzed Tiger Beetle! Their fast-running and fast-flying behaviour is one way of identifying these members of the beetle family. The adults fly or run down their prey and can capture both walking and flying insects! They are native to Canada and are not commonly found in our area, especially this early in the spring!

A beautiful day of sunshine and warm temperatures woke up many insect species! An Eastern Comma was lined up with the flies to have a taste of sap.

A Mourning Cloak recently played "peek-a-boo" with me!

Small Milkweed Beetles are in the family of Seed Bugs. Most are plant-eating, feeding on seeds and sap of host plants. Some species are predaceous and feed on other insects.

Plants that don't have bright and colourful flowers often have flowers with a strong odour. The odour helps to attract early season pollinators including Western Honey Bees!

Cellophane Bee

Cellophane Bees are already active! I located two groups of these ground bees which were searching for mates. (pair mating in centre of above photo) I counted approximately 75 bees hovering sightly above ground at one location and 50 at another. They emerge in early spring, creating small holes in the ground for nesting. Unlike honey bees, they don't form hives, but live in groups. They waterproof their nests with a unique glue-like secretion while also serving as vital pollinators for early blooming plants.

Lots of creatures are happy that insect food is available!

I was "shocked" when a Golden-crowned Kinglet perched for a rest. These birds seem to be in perpetual motion as they search for insects to eat. Perhaps it had a full tummy!

Northern Flickers have returned in large numbers.  Although it can climb up the trunks of trees and drill on wood like other woodpeckers, the Northern Flicker prefers to find food on the ground. Ants are its main source of food, and the flicker digs into the dirt to find them. It uses its long barbed tongue to lap up the ants. If you look closely, mud is visible on the beak of this bird!
