Eastern Chipmunk - Grande Allée - The Grand River - The Backyard

 Eastern Chipmunk (Tamias striatus)

     This is the third (and last) of the squirrels that live in our area.


     Eastern Chipmunk is a great favourite with everyone, especially children, who seem drawn to this little rodent with its pin-striped charm. The fact that it will feed from your hand almost without hesitation does nothing to diminish its appeal.


     Its small size and relatively low weight mean that it can evade most devices designed to restrict squirrel access to bird feeders, and it dines with impunity. 


     When they are on a mission to build up winter storage they make trip after trip to their den, cheeks bulging, and seeds set out for the birds can be depleted in short order.
     But who can resist their charm? They climb up onto the chairs while we are relaxing on the patio and it is hard not to succumb to the notion that they enjoy human companionship.


     Chipmunks are solitary, or sometimes live together in small family groups. 
     They are mostly vegetarian, but do not eschew June Bugs, earthworms, grasshoppers and even frogs. Given the chance to raid a bird's nest, eggs form a tasty treat. Gardeners are not always enamoured of chipmunks for whom bulbs and corms are a welcome addition to their diet.
      The list of predators is long and constant vigilance is required to survive. Foxes, coyotes, weasels, raccoons, skunks, and birds of prey all include chipmunks in their diet. In urban areas domestic cats are a constant threat. Often well-fed tabbies will simply decapitate the chipmunks and leave their headless carcases scattered around. Cat owners take note!


     I can hardly wait till spring when we will see them again.

Grande Allée and the Grand River, Cambridge, ON

     I have pointed out to those who should care that the sign is incorrect, but it looks like that is how it is going to stay.


     Even a Grade One pupil would be appalled, but correct French Grammar is obviously unimportant to some.
     The trail meandered on from the road.


     A vagrant Harris's Sparrow (Zontrichia querula) had been reported at this location, so we decided to start our regular Tuesday walk there.
     The bird had been seen at 07h:30 but it did not show itself while we were there.
     Blue Jays (Cyanocitta cristata) were plentiful, however, resplendent in their cerulean beauty.


     We were delighted to see a couple of exceptionally handsome Red Fox Sparrows (Passerella iliaca), always a great sighting.



Grand River, Cambridge, ON

     Having spent about an hour and half searching for the Harris's Sparrow and enjoying the Fox Sparrows, we decided to go down to the Grand River to check on the waterfowl.
     Common Mergansers (Mergus merganser) were indeed exactly that - common. Here are a couple of males.....


     ..... and a female.


     We were reminded that a Mallard (Anas paltyrynchos) is an exceedingly handsome bird.


     Years ago, I used to run into an expatriate Brit quite frequently, who had a broad Birmingham accent and always referred to Mallard drakes as "stunners." Stunners indeed. 
     There was a small flock of Buffleheads (Bucephala albeola) - the local ladies club perhaps since they were all females.


     Far down the river we could see a pair of Hooded Mergansers (Lophodytes cucullatus) but only the male is visible in the picture below, along with Common Mergansers and an American Herring Gull (Larus smithsonianus).


     Bruce Spanworm (Operophtera bruceata) is a common moth in November, its appearance seeming to coincide with the first snow.


     An American Red Squirrel (Tamiasciurus hudsonicus) was its usual argumentative self.


     Mostly keeping company with the Buffleheads a single female Common Goldeneye (Bucephala clangula) dove repeatedly, as did all the other diving ducks present.


     One must assume that the biomass of freshwater mussels, crayfish and other items sought by these ducks is substantial.
     Ring-billed Gulls (Larus delawarensis), sated perhaps, seemed content to loaf together.


     A rock always provides a good perch.


     A herring gull was not to be outdone.


     Canada Geese (Branta canadensis) seemed to be enjoying a collective snooze.


Grande Allée, Cambridge, ON

     We decided to return to Grande Allée (less than ten minutes away) to see whether the Harris's Sparrow had appeared again, but no such luck. A small gathering of expectant birders waited patiently.
     Several Dark-eyed Juncos (Junco hyemalis) came to feed.


     They were joined by that most delicate of our native sparrows, American Tree Sparrow (Spizelloides arborea).


     And to bid us farewell another Fox Sparrow joined the fray.


Fountain Street Bridge, Cambridge, ON

     A pair of Bald Eagles (Haliaeetus leucocephala) have bred successfully at this location, and one of the pair (presumably) was perched adjacent to the nest.


     Not a bad way to end the morning!

Our backyard, Waterloo, ON

     For a while our backyard resembled Central Station at the rush hour!
     We have found that suet blocks impregnated with capsicum are effective at keeping the squirrels from gorging on it, but are equally enticing for the birds as untreated suet.
     A Hairy Woodpecker (Leuconotopicus villosus) returned several times and chiseled away.


     A Red-breasted Nuthatch (Sitta canadensis) found it no less appealing.


     I have mentioned in previous posts that American Robin (Turdus migratorius) is no longer uncommon in the winter and this individual was efficiently gleaning seeds spilled from the feeders above.


     House Sparrow (Passer domesticus) is a species whose population has plummeted and often several weeks pass when we don't see them in our yard.




     A Blue Jay is always a welcome visitor.


     "If you've got it, flaunt it," this Northern Cardinal (Cardinalis cardinalis) seems to be saying. 


   
 A male House Finch (Haemorhous mexicanus) vies with the cardinal for attention. 


   
 If I were to speculate on which species is the most frequent visitor to the backyard this year it would be Dark-eyed Junco.


     A male Downy Woodpecker (Dryobates pubescens) came to partake in the feast.


     Such an interesting display of its underwing as it left.


     Mere moments later a female took its place.


     And these are only the species we captured on camera. There were more! 
     We'll have to see what we can bring you next time.

Highlights From Here and There

      This post represents a few highlights from recent walks, and events at home, with no theme other than nature is on display!
     The Butterfly Milkweed (Asclepias tuberosa) which provided such a stunning burst of colour when in bloom, has gone to seed, but is no less spectacular.


     Mother Nature weaves her magic tapestry in many different ways.

Backyard Highlights and Other Delights (And Lily)

If you listen to birds, every day will have a song in it.
Kyo Maclear

22 July 2021
Our Backyard, Waterloo, ON

     A female Hairy Woodpecker (Dryobates villosus) visited our backyard for a couple of days and seemed to show interest in a nest box that was clearly too small for it, with an entrance hole that would barely permit the bird to squeeze inside.


     She has moved on so I assume that she came to the same conclusion!
     Our backyard wouldn't be the same without a couple of Eastern Chipmunks (Tamias striatus) to entertain us.


     They rank high on the adorability scale and can become very confiding when a little food is offered.
     Male House Finches (Haemorhous mexicanus) are exceedingly handsome birds and these two fed together at the same feeder without so much as a ruffled feather.


     A female came along and supplanted one of the males; perhaps romance was on her mind.


     For several weeks a Northern Cardinal (Cardinalis cardinalis) missing his head feathers has been visiting us. 


     I can't quite figure whether this is a protracted moult or feather mites are at work, although there does seem to be a hint of new feathers emerging. It is not hard to appreciate the dinosaur origins of birds when you see a cardinal in this condition.
     Here is what we are more used to seeing.


     A Chipping Sparrow (Spizella passerina) is a delicate and beautifully plumaged little bird, and we are always happy to see them in our yard.


     Not quite so welcome is a rat (Rattus sp) that visits from time to time.


     Despite our best attempts to trap it we have failed so far, capturing only chipmunks and a Mourning Dove (Zenaida macroura) but we will keep on trying. Its reward will be a long ride into the countryside where it will have the pleasure of starting a new life.
     Mourning Doves seem to be the most placid of all birds and find a quiet place to rest and watch the goings-on of others, quite detached from the hustle and bustle taking place around them.

Our Backyard, Waterloo, On

     Small moths that come to rest on the walls of the house, or in the porch, usually fly away before we get a chance to photograph them. Not so with these two.

Common Idia Moth (Idia aemula)

Dark-barred Twin-spot Carpet (Xanthorhoe ferrugata)

     Monarchs (Danaus plexippus) have discovered the milkweeds (Asclepias) and this female is ovipositing. 


     We will be sure to keep a keen eye for caterpillars when they emerge.

Questions Posed by Elaine

     A regular reader of my blog, Elaine, has posed a variety of question regarding birds and their breeding biology and lifestyle. I have committed to answer them a few at a time, so here are a few more.

Q. Does the number of eggs laid vary from the first to subsequent clutches?
A. Not always. Some birds, American Robin (Turdus migratorius), for example, routinely lay two clutches,  each containing four eggs. In other species second clutches may contain fewer eggs, especially if the food required by the female for egg formation is in short supply.




Q. Are juvenile birds from the first batch more successful migrating?
A. If the young birds are fit and healthy at the time of departure the migratory outcome is the same. Condition at the time of departure is the key factor.


Q. Do (formerly) juvenile birds return to the location where they were born the following year?
A. Rarely to the exact location, but often to the same area. However, if pair formation occurs away from the breeding site, as with waterfowl, for example, it is unlikely that both partners will have been born in the same area; therefore one of the pair will not return to its natal territory. There is a wide variation across a range of species.

Q. Do "our" birds also nest in their migratory destinations.
A. No. Before departure their reproductive system shuts down and their gonads shrink. Superfluous weight impedes migration. A return to reproductive viability does not happen again until the following spring, when a whole series of factors combine to stimulate and reactivate the endocrine system.

Health Valley Trail, St. Jacobs, ON
     

     American Herring Gull (Larus smithsonianus) is far less common than Ring-billed Gull (Larus delawarensis) at this time of the year, but for some reason this section of the Conestogo River seems favoured by the few that spend the summer here.


     Conditions seem to have been just right for Eastern Black Walnut (Juglans nigra) and the fruit crop is impressive.


     It is often located in close proximity to a river or stream, and I have seen it over the past few days along both the Grand and Conestogo Rivers.


     Miriam and I arrived a little earlier than Heather and Lily, and Lily waved a cheery hello.


     A stately Great Blue Heron (Ardea herodias) moved along the river stealthily in search of prey, pausing now and then.


     A young bird still has much to learn and might benefit from keeping a keen eye on a skilled adult.


     Lily was intent on taking it all in.


     Many hungry mouths at an American Cliff Swallow (Petrochelidon pyrrhonota) colony were keeping parents busy delivering food to their young.


     
Chicory (Cichorium intybus) was blooming everywhere.


     A Furrow Bee (Halictus sp.), well dusted with pollen, evidently found it attractive.


     Several young Cedar Waxwings (Bombycilla cedrorum) were honing their flycatching skills.




     A couple of American Robins just seemed to be enjoying each other's company.


     Upright Hedge-parsley (Torilis japonica) is an attractive plant, thriving even in depleted soils.


      The sign on this bench left us a little puzzled, and the addition of a vase of roses only added to the mystery.


     The pond damsel below is in the genus Argia. Only two species are found in the province, both in similar habitat, and not entirely unalike in appearance. I am pretty sure, however, that this is a Powdered Dancer (Argia moesta).


     Both species are prone to alight on bare ground like this, and are surprisingly quick when approached.
     Common Fibre Vase (Thelephora terrestris), also know as Earth Fan, is an interesting fungus.


     Turkey Tail (Trametes versicolor) is another common bracket fungus of our area.


      Neither Miriam nor I can could instantly identify this pretty pink flower, but Heather, hearkening back to her time spent as a field biologist, knew instantly that it is Deptford Pink (Dianthus armeria).


     At the end of our walk we decided to go for an ice cream. Heather thought she would get away with giving a lick or two to Lily. Fat chance!



     Lily grabbed onto that cone and wasn't relinquishing hold for anybody!


     Amazingly she started at the top and worked her way down and hardly even made a mess.


     Next time it will have to be one extra, Heather!
