Fly baby fly! The baby eagles are fledging.

fledgling eaglesThose of us who live around here sometimes take the bald eagles for granted. We forget that they’re not common in all parts of the country. But we never tire of seeing them and their majestic white heads and enormous wingspans. This time of the year is particularly wonderful as we’re regularly seeing eagles (it’s not uncommon to see 5-12 in one trip) and we’re seeing the fledglings.

So what’s a fledgling or fledging? Fledging is when the baby eagles, aka eaglets, learn to fly. It comes from the term fledge which refers to when the babies have acquired the feathers and wing muscles necessary for flight. The first flight usually happens around 10 to 13 weeks after hatching so what we’re seeing now are the babies who hatched sometime in June.

Once the young eagles have fledged, they remain around the nest for 4 or 5 weeks, taking short flights while their primary feathers grow and strengthen. Their parents still provide all of their food.

Recent sightings

Rarely do you see baby bald eagles but we’re seeing them pretty much on every trip. We currently have 4 nests on our stretch of the river, although only 2 of the nests can be seen from the rafts. In the past two weeks, we have taken 186 trips. We have seen 1,446 eagles (958 adults and 488 immatures) on those trips, which brings the average to 7.77 eagles per trip. There was only 1 of the 186 trips that did NOT see an eagle! We have seen as many as 14 individual eagles on one trip during the past 2 weeks.

What we’re seeing as they fledge are their attempts at flight and fishing and learning life on their own. It’s pretty fun to watch. Currently we’re also seeing multiple nesting pairs along the river which is unusual. The female eagle generally lays one to three eggs. Sometimes three chicks will hatch but competition in the nest is so high that generally only one or two will survive. But we are seeing more of the multiples.

The adult eagles tend to fish early in the morning to feed their babies. So the 8 or 10 o’clock floats can sometime catch this action. Not an early riser? Not to worry. As you can tell by the numbers above, it’s extremely rare not to see eagles on a trip.

So if you’ve always wanted to see baby eagles, now is the time. But they’ll be flying off on their own soon so don’t wait too long to book a trip.

Grand Teton National Park: The park that almost wasn’t

Grand Teton National ParkIn addition to seeing amazing wildlife and stunning views, one of the things our guests always comment on about our scenic float trips is how much they learn from our guides about the history, geology and botany of the Park. So we thought we’d spend some time in our next few blog posts sharing a little about those things. Today it’s history.

We are incredibly lucky to have Grand Teton National Park. The formation of the park was one of the longest, most bitterly fought of all American conservation battles. It took 50 years and three separate governmental acts (holy cow!) whereas Yellowstone (the nation’s and the world’s first national park) took only two years from idea to reality.

The early years of Grand Teton National Park

As early as 1897, several proposals suggested expanding Yellowstone’s boundaries southward to encompass portions of northern Jackson Hole and protect migrating elk herds as well as including the Teton Range and northern Jackson Hole. Neither the Department of the Interior nor Congress acted on these early proposals. A small version of today’s park was eventually established in 1929, protecting the major peaks of the Teton Range and six glacial lakes at the base of the mountains. But much of the valley of Jackson Hole remained in private ownership so conservationists decided to seek private funds to purchase land in the Jackson Hole valley. …continue reading Grand Teton National Park: The park that almost wasn’t
