Rouge National Urban Park - Birds的日誌

The Eastern Bluebird, part of the Thrush family that include relatives such as the Hermit Thrush ,Wood Thrush, Veery and American Robin.
The maps in most bird guides show the bluebird as a Summer/breeding resident in this part of southern Ontario. It seems though that more and more Eastern Bluebirds are now overwintering and becoming year-round residents in this part of the province including the Rouge National Urban Park. These birds make their nests in tree cavities or excavated holes drilled out by Pileated Woodpeckers. They are also quick to put to use the many bird boxes installed within the Park. Surely this has helped boost their numbers now residing in the area.

Whoo…, Whoo…, Whoo…, Whoo. If you’re lucky enough to hear that sound you might be in the vicinity of a Long-eared Owl.
Primarily a nocturnal hunter but usually starting at dusk and finishing just before dawn. These owls patrol over open fields, clearings and grasslands. They fly silently along, a couple metres above the ground listening intently for any prey that passes beneath them. Sensing their favourite meal (Voles) they pounce down and catch by their sharp talons, then kill by biting and crushing the neck or back of the head before swallowing whole.

This Owl with its long ears which aren’t actually ears but tufts of feathers (its real ears are on the side of its head ), orange facial disk and big yellow eyes have @galloots13 locked in its sight!

The Pileated Woodpecker. Everbody’s favourite Woodpecker!
This of course is Canada’s largest woodpecker measuring between 16 and 19 inches in length. Usually heard before seen. Either drumming away at a tree where it excavates its large trademark rectangular hole in search of ants, beetle larvae and other insects. Else reminiscent of Woody Woodpecker the cartoon character loudly calling its laugh-like Cuk-Cuk-Cuk-Cuk for all to hear.

This months sighting by @kellysteele . With its bright red crest contrasting against its white neck and black body and with the Autumn colours of the forest serving as a backdrop, this made for October’s sighting of the month. Pictured here is the male with the identifying red cheek stripe.

Wilson’s Phalarope a relative of the Scolopacidae family (Sandpipers and Allies). These waders breed primarily in shallow prairie lakes, marshes and mudflats on the plains of Western Canada. Records of smaller isolated individuals have been documented in Ontario. Wilson’s Phalaropes are long distance migrants spending their winters on Salt lakes and ponds in the Andes as well as marshes and wetlands in southern South America. Phalaropes are sometimes observed swimming/spinning in circles creating a whirlpool effect that brings small insects and invertebrates to the surface to feed upon.

This months sighting by @pinemartyn . With its needle like bill this Phalarope was seen foraging in the marsh on it’s own.

It’s not yet Fall but the migration back down south has already begun. Many shorebirds including the Lesser Yellowlegs spend their summer breeding season in the Boreal forest region of North America. They are typically seen in Southern Ontario on their way back down to the Gulf coast, Central America and South America where they will overwinter.

Slightly smaller and with a shorter straighter bill then its larger lookalike the Greater Yellowlegs. The Greater Yellowlegs bill is slightly upturned and is sometimes slightly lighter in colour at the base. Typically the Lesser Yellowlegs bill is the same length as its head whereas the Greater Yellowlegs bill can be one and a half times as long as its head, but length can vary.

This month’s sighting is of a Lesser Yellowlegs by @marlene-d. This individual is seen on it’s lanky yellow legs wading through the Water lilies, stirring the waters about with it’s long bill in search of various insects, bugs, flies and small crustaceans.

Out and about this month in the Rouge Park this Blue Jay calling from above caught the attention of @pinemartyn.
The feathers of birds wear out over time and need to be gradually replaced. In the case of Blue Jays they sometimes drop (molt) all their capital head feathers at the same time in which they go through a bald phase lasting for a week or two.

The Pied-billed Grebe, One of three Grebes that breed in Ontario. Usually found in quieter marshes , bays, small ponds and even sewage lagoons. The Grebe patrols these still waters in search for its varied diet of crustaceans, small fish, frogs and insects.
Able to control their buoyancy by trapping and releasing air between their feathers, Grebes sometimes swim about stealthily with only their head above the water resembling a submarine with periscope in the up position.

This months sighting by @gary-james .Sporting his namesake pied-billed (having two or more colours) beak this Grebe paddles quietly along the calm pond waters.

Considered at one time to be it’s own species, DNA testing now shows that the Lawrence’s Warbler is a hybrid between the Golden-winged Warbler and the Blue-winged Warbler. The offspring of these two species can sometimes take on two different looking hybrid forms depending on the genes that are passed on.

When the recessive genes for a black throat and overall yellowish plumage are passed on you get the rarer Lawrence’s Warbler hybrid.
When the more dominant genes are passed on you get the more common Brewster’s Warbler hybrid which lacks the black throat and is lighter in colour overall.

This months observation by @pinemartyn is of the Lawrence’s Warbler hybrid (Golden-winged × Blue-winged Warbler) with it’s black throat and mask and overall yellow plumage.

May brought with it a flourish of bird activity in the Rouge National Urban Park. Birds were busy building nests and at the same time fattening up on emerging insects. Birders were out looking and listening for Spring Warblers. In the park 15 different species of Warblers were observed this month. Among them, Canada, Mourning, Blackburnian and Chestnut-sided Warblers. As usual the Yellow Warbler was the most frequently observed.

May Warbler numbers:

But this months sighting is not of a Warbler but of the secretive Cuckoo. In Ontario we have 2 different species of breeding Cuckoos, the Black-billed and the Yellow-billed Cuckoo. Woodland edges and thickets are their preferred habitat. Here they hop about small trees and shrubs looking for caterpillars (often tent caterpillars) and grasshoppers which is the main staple of their diet. Spongy moths which we have plenty of in the park are also thought to make up a portion of their food supply.
If you’re wondering why they are called Cuckoo birds it is from the sound they call out. But it is the Common Cuckoo found in Europe that makes the namesake “cuckoo -cuckoo” sound. All other species in the Cuckoo family including the Black-billed Cuckoo have different but loud vocal calls.

Spring is now well under way in the Rouge National Urban Park. As the temperatures slowly rise so do the number of bird species seen in the park. This month 76 species of birds were observed and documented in the park on Inaturalist compared to only 54 last month.

This month’s sighting is of an early returning Great Egret by @pinemartyn . Our second largest of the Ardeidae (Herons, Egrets and Bitterns) family in Ontario. Only the Great Blue Heron being larger. Dressed in white with an S shaped neck the Egret appears a stately regal figure. During breeding season its facial skin has turned from yellow to a brilliant green. It has also grown in its long wispy trailing feathers that are spread out during courtship displays.

To many avid birders Spring means WARBLERS! And on schedule @firebreathingcookie was the first Inaturalist user to observe a returning Warbler to the Park on April 17, 2023.
Black, grey and white with yellow patches on its cap, sides and rump. This Yellow-rumped (Myrtle) Warbler can almost blend into the yellow flowers of the Forsythia shrub it has alighted upon.

The last few days of March started a “Wild Goose Chase” for many in the birding community. Rarely seen in North America a Pink-footed Goose was first spotted in the Duffins Creek Corner Marsh in Pickering on March 30th. At some time the next day it was seen feeding in one of the many agricultural fields within the Rouge National Urban Park. Many birders were out and about hoping to get a sighting of this goose, a lifer (first time sighting) for many.

The Pink-footed Goose makes Greenland and Iceland its summer breeding grounds. It typically spends its winters in Northern Europe but occasionally has turned up in Eastern North America.

This months sighting by @adam_capparelli . After spending some time feeding in an agricultural field within the Rouge National Urban Park this Pink-footed Goose (middle) took flight with a group of Canada Geese. Eventually they returned to nearby Reesor pond where they spent the night.
