Beyond the reflection: the dangers of windows

Aug24

Posted by Matthew Sim

As the fall migration starts to heat up and southbound warblers, vireos, flycatchers, sparrows and more pass through Calgary, birding can become quite exciting. While for us, this is a great time to be out and about, for the birds, it is dangerous; very dangerous. Migrating passerines (perching birds), for example, have to travel long distances all while on the lookout for predators such as hawks and cats, try to get food themselves and hope they don’t get caught in an early cold-snap which could potentially kill them. And this is just the beginning, there are even more dangers; one of them which is the most lethal of them all.

According to Sibley Guides Bird Mortalities, window strikes (when a bird hits a window) kill between 97 and 976 million birds each year, more than any other cause of bird deaths. (http://www.sibleyguides.com/conservation/causes-of-bird-mortality/).  I was in my neighbor’s yard when I noticed one of these fatalities on his patio. While I had been there, a migrating Ovenbird had struck his window and had died. Though birds can crash into  windows at any time of the year, window strikes tend to happen more frequently during migration as an influx of migrants come through unfamiliar territory, passing from tree to tree. As you can see in the photo below, it is quite easy for a bird to see its habitat reflected in a window and believe that it is simply another tree they are heading to; I’m sure most don’t know what hit them.

If I were a bird, I would probably fly towards these trees too.

Many bird populations are declining already due to a number of reasons and we don’t need to help them along with  reflective windows when we could easily prevent window strikes occurring.

This Ovenbird had struck my neighbor’s window while I was in his yard.

Probably the worst part of all this is that window strikes are senseless; it’s not like natural selection where it was meant to happen, window strikes are part of our devastating side effects on nature; however, they can also be easily prevented.

There are many ways to prevent birds from striking windows. If you are having birds fly from your feeders or bird baths into windows, you can either move these bird attracting features further away (25-30 feet) from the window or closer (1-3 feet) to the window so that if the birds do hit the window at just 1-3 feet they will not be going fast enough to do any harm to themselves.

Apparently, there is also a material called CollidEscape which can reduce reflectivity and transparency on the outside but still leave the windows transparent from the inside. You can check it out here.

Here are a few more options:

  • plant shade trees outside windows to break down reflections
  • install snap-on window dividers
  • put a hanging plant outside of the window

These are just a few of the ways you can avoid window strikes and help reduce the number of avian mortalities each year. Often, preventing window strikes can be as simple as closing the curtains or blinds when not using the windows. You can see even more solutions here.

If you have birds hitting your windows, there are many ways to stop it; help out bird populations!

Sunday Showcase: Spotless Spotted Sandpiper

Posted by Matthew Sim

Okay, try saying that 10 times fast. Spotted Sandpipers, while spotted in their breeding plumage, do not have spots in winter or when they are juveniles.  Juveniles can be separated from winter plumaged birds by the scaling and barring on their upperparts, which nonbreeding adults do not have. Right around now, we start to see juveniles so look out for them; I recently found this juvenile in Votier’s Flats in Fish Creek Provincial Park.

 

 

Clash of the herons

Jul27

Posted by Matthew Sim

On a recent bike ride of mine to Votier’s Flats in Fish Creek P.P. I came across a juvenile Great Blue Heron in a storm water pond so I got myself into a good position to photograph it. I sat watching and photographing the heron for some time when suddenly, an adult Great Blue flew in.

Juvenile Great Blue Heron

A rather impressive landing…

The adult heron seemed to “own” the ponds and did not take kindly to the young heron fishing in his waters. The adult proceeded to hunch himself up in a bid to frighten the juvenile.

All hunched up, the adult Great Blue proceeded to hurriedly chase the juvenile around the pond until finally the young heron took a running start and flew off.

Taking off with a running start.

Far from being content however, the adult flew after the young one and the two of them disappeared over the hills. I didn’t move from my position however, because I had a feeling that at least one of the herons would be returning. Sure, enough, several minutes later, the adult returned finally content at having chased the young upstart off of his territory.

Finally able to relax and scratch his head.

Birding the Lafarge Meadows ponds

Jul5

Posted by Matthew Sim

In the last few weeks, I have made several trips on my own down to the sloughs at Lafarge Meadows. There is always action there; be it coots feeding young ones, Pied-billed Grebes fishing, Ruddy Ducks courting, Red-necked Grebe diving or Yellow-headed Blackbirds chasing every other bird.

One of my favorite parts about the Lafarge Meadows sloughs are the Red-necked Grebes. I have counted as many as 4 pairs at a time on the ponds and have also enjoyed watching them court side by side.

Red-necked Grebe

The Red-necked Grebe is not the only grebe that can be seen at the ponds. The smaller Pied-billed Grebe also calls the sloughs home.

Pied-billed Grebe

So far, I haven’t seen any young Red-necked Grebes but I have seen several families of Pied-billed Grebes.

There are also several other families on the ponds, including Mallards and Common Goldeneyes.

And while I was enjoying these great sights; I couldn’t forget the birds that truly make a southern Albertan slough like the Ruddy Duck, the American Coot, the Yellow-headed Blackbird- and of course, on the mammal side of things, the Muskrat.

Bird Profile: Tree Swallow

Jun16

Posted by Matthew Sim

During the summer, Calgary is home to 5 species of swallow; Barn, Cliff, Bank, Northern Rough-winged and Tree Swallows can all be reliably found in the city during the warmer months. The Tree Swallow, perhaps the most common species of swallow here is a favorite bird of mine because of their personality. They always seem to be communicating with one another and I find it humorous to sit back from time to time and watch as a pair on a branch lean back and forth, chattering away to each other.

The Tree Swallow is, of course, a member of the swallow family, (the family is known by the latin name Hirundinidae) small, slender songbirds with small bills and long, pointed wings. A swallow’s sleek form allows it to be an “adept aerialist”, as described in the National Geographic field guides, and they use this form well as they are always darting and swooping about catching flying insects.

The Tree Swallow is separated from other swallows by its blue-green feathers on its upper parts and white plumage below.

Identified by its blue-green upperparts and white underparts,  the tree swallow can be seen flying around meadows and open fields and in wooded habitat near water, such as down along the river in Fish Creek. In fact, just last week as I was exploring some trails in Fish Creek Provincial Park by the river, I came across a Tree Swallow nesting in a cavity right at eye-level in a poplar tree.

Down in that hole, just out of eyesight, is the Tree Swallow’s nest, which is an open cup of grass lined with plenty of feathers- most will likely be from waterfowl on the river. As the Cornell Lab of Ornithology says about these guy’s nests; “the Tree Swallow uses many feathers from other birds in its nest. The feathers help keep the nestlings warm so they can grow faster. They help keep levels of ectoparasites, like mites, low too.”

Now, perhaps, you know a little bit more about these beautiful and graceful birds. I know that I learned quite a lot as I did research for this post. And though you probably see plenty of Tree Swallows during the summer here in Calgary, next time you see one, I want you to stop and just observe it for a while; I’m sure you will see that they have lots of character!

A Sharp-shinned in my yard

Posted by Matthew Sim

The other day, I was sitting outside in my yard, soaking up some sunshine when I heard a big commotion coming from the spruce tree in my yard. There were Grackles, Robins, Blue Jays, Pine Siskins, Chickadees and Red-breasted Nuthatches all making as much noise as they possibly could. The reason? Look at the photo below; do you see anything?

How about now?

Though the Sharp-shinned hawk was rather well hidden, it couldn’t hide from the neighborhood birds who know all too well what will happen if they leave this predator undisturbed.

Here are some more photos of this beautiful bird.

A Big Day in Fish Creek

Jun10

Posted by Matthew Sim

This past Friday, I did a Big Day in Fish Creek. For those of you who do not know what this is, a Big Day is when you try to see and hear as many species as possible within a 24 hour day. For my Big Day, I spent more than 10 hours in Fish Creek, doing the entire day by bike, riding about 74 kilometers (46 miles) throughout the park and recording 93 species of birds, falling short of my goal of 100. Temperatures ranged from 6-15 degrees Celsius and there were a few showers. I started at about 5am and took a 2 hour weather break at lunch time, hoping for some of the rain to blow over, before returning at 2 and counting for another 3 hours. A full list and a more detailed report of the day can be seen here: http://groups.yahoo.com/group/Albertabird/message/20841

Here are some photos from the day:

Hummingbirds of the Weaselhead

Jun9

Posted by Matthew Sim

This past Thursday, I went out for a walk in the Weaselhead with local nature expert Gus Yaki and a group of other birders. Our target species were the 2 species of hummingbird that call this park home; the Calliope Hummingbird and the Rufous Hummingbird. Though we saw and heard many great species on our walk, for this post I will concentrate on the hummingbirds.

When we reached the area where Calliope Hummingbirds are usually seen, we scanned around with our binoculars, searching for this tiny bird. The smallest bird in North America at 8cm in length (3.25 inches), this hummingbird can sometimes be passed off as a large bee. After several minutes, somebody found this beautiful male perched at the top of a spruce tree.

Male Calliope Hummingbird

We observed this little guy (the Calliope is the smallest long-distance avian migrant in the world) as Gus told us many neat facts about the species. For example, the pink streaks on the male’s throat form a V-shaped gorget, and these streaks are rather long, so that when the male turns his head, the streaks will actually reach back over his shoulder. This was my first time seeing the species so I was particularly enthralled with the bird. After some time, we moved on, back closer to the river in search of the Rufous Hummingbird.

We had to walk through some muddy spots to get to the habitat where the male Rufous is likely to be seen but was it ever worth it! When we got there, someone soon spotted the male Rufous and we soon all had our binoculars trained on him as he displayed his gorgeous orange-red gorget.

Male Rufous Hummingbird

The Rufous Hummingbird was moving around a lot and we got to see him at various spots; perched and in flight.

At one point, he even came to the bushes right behind us and started feeding.  Gus told us that these bushes were actually Siberian Peashrub, more commonly known as Caragana. They are an invasive species that totally dominates the environment, so that no other flowering plants live in the area ( it covers 10-12 acres on the north side of the Elbow river). Male Rufous Hummingbirds  feed on these plants because of the abundant if  only temporarily nectar, however the females, which raise their families alone without the help of the males, realise that there is not enough nectar to raise a family on and head elsewhere, to richer, more natural environments. The males are then at a biological dead-end and do not have the oppurtunity to pass on their genes. This was quite fascinating and I would not have learned this had I not been on the trip with Gus. Thanks Gus!

He showed off his colors beautifully, revealing how he got his name.

We had a great morning watching these hummingbirds and learning lots about them thanks to Gus’ vast wealth of knowledge.

Weekend Photos

Apr23

Some great pics sent to us by folks out birding over the weekend!

We had an interesting Saturday afternoon at the Inglewood bird sanctuary with two unusual events.  First we had a Long-eared owl sighting, and then observed a mink “running” away from an upset nesting goose.  Byron and Cheryl

Gianfelice also had a great birding day on Saturday, with sightings of both a winter visitor and a returning spring migrant. The White-winged Crossbill and Eastern Kingbird were photographed at Weaselhead. [UPDATE: After this post went up, it was pointed out to us that the bird below is likely an Eastern Phoebe, not a kingbird. It is lacking the white tail tip, and it is very early for kingbirds to return to Calgary. Pat will no longer be making snap judgements on bird ID’s and thank you Gus for the correction!]
