Nature wise: Common tern and Bonaparte91裸聊视频檚 gull are fishing buddies

A column by Dianne Bersea

I love it when unexpected wildlife situations occur.

Every season provides different bird arrivals and departures as various species pass through my Okanagan 91裸聊视频榟ood91裸聊视频. These days Fall birds are returning from a breeding summer in the north, heading south for Central America or even further.

Thus it wasn91裸聊视频檛 a big surprise to spot a bird that I hadn91裸聊视频檛 seen for awhile. From a distance I thought it might be a gull. But it91裸聊视频檚 feeding pattern over a shallow area of the lake91裸聊视频uick turns, dashing surface skims with abrupt dives for fish fry91裸聊视频eft me mystified.

Hmmm. Who is this?? As it streaked by closer to me, I could see mostly white sharp-pointed wings, with a greyish head marking on a small aerodynamic body.

Speculating with my birding partner, we settled on a tern, but which one? Before that thought could be more developed a similar but different bird swooped in and began a somewhat similar fishing technique. Clearly they were two different birds with similar size, shape, wingspan and fishing approach.

After studying our photos, we identified the second bird as a juvenile Bonaparte91裸聊视频檚 gull and the first as a Common Tern, early representatives of the many that would be passing through shortly.

Curiously, they seemed to be congenial fishing buddies91裸聊视频topping for a break, then off fishing again, then stopping for a break. The 91裸聊视频榖uddy91裸聊视频 idea felt confirmed when they appeared to fish and rest in the same location the next day. When we proposed this idea to a very knowledgeable birder friend, he said, 91裸聊视频淭hat91裸聊视频檚 known,91裸聊视频 in a casual manner I took to mean, 91裸聊视频淲ell, of course!91裸聊视频

That also confirmed bird sightings of some years before. In the Okanagan shrub and ponderosa pine 91裸聊视频榖ack 4091裸聊视频 where I lived at the time, I91裸聊视频檇 spotted flocks of birds that seemed to arrive, feed and depart together.

I continued to notice similar mixed flocks throughout the year, especially during Fall & Spring when choice food options were available.

That91裸聊视频檚 what flocking together is all about, similar & abundant food hunting requirements! Add team benefits such as a 91裸聊视频渘uclear91裸聊视频 species around which a flock might form, sentinel species that keep an eye on potential danger, and associates that join in when flock is moving through.

I recall seeing mixed flocks of similar sized birds arriving together that included chickadees, finches, sparrows, nuthatches, juncos and my favourite surprise visitor91裸聊视频ed crossbills.

They91裸聊视频檇 arrive as a flock and land in prime feeding spots91裸聊视频n wild roses, Saskatoon and snowberry bushes, some breaking away to branches on the Ponderosa pines and shaggy Douglas fir.

In a flurry of focused busyness, they91裸聊视频檇 feed on their preferred snacks. The nuthatches choosing tree bark inhabitants91裸聊视频he black-capped chickadees seeking berries, seeds, and insects, their diet for most of the year.

In about twenty minutes of energized feeding activity, intense bird chatter and a splash in the birdbath, they91裸聊视频檇 whirl away again.

Apparently it91裸聊视频檚 not unique for birds to travel and feed together. Perhaps that91裸聊视频檚 how this saying originated91裸聊视频91裸聊视频滲irds of a feather, flock together.91裸聊视频
