As of late, seeing a bald eagle nest is not that massive a deal. It definitely was in 1979. That 12 months, there have been solely 4 nests identified in Ohio. The magnificent raptor was on its manner out, largely the sufferer of DDT poisoning.
Dichlorodiphenyltrichloroethane (good factor for acronyms!) Was a pesticide generally used for agricultural functions. When it made its manner into the meals chain, the impression was disastrous on sure chook species. Within the case of the bald eagle, DDT weakened egg shells, stopping profitable hatches.

Richard Nixon was inaugurated on Jan. 20, 1969, and one in all his first main initiatives was addressing environmental points. He signed the Environmental Safety Company into existence on Dec. 2, 1970, and one of many fledging company’s first actions was to ban DDT. That occurred in the summertime of 1972.
The restoration of bald eagles following the DDT ban was a gradual highway. By 1989, there have been a dozen nests in Ohio, and by 2000 practically 60 nests have been identified.
The majestic nationwide image is off to the races now. The Ohio Division of Wildlife estimates there are over 800 lively nests in 2022, a meteoric improve.
Taking a gawk on the hawk
I’ve seen an amazing many eagle nests through the years, however nothing just like the one which I noticed on June 3. Photographer Stephanie Gaiser despatched me a observe a couple of nest not removed from Dublin during which one of many chicks was decidedly not just like the others. Her story impressed me to go to instantly.
Upon arrival to the nest, the 2 huge eagle chicks caught out like sore thumbs. However, wait! Proper between them was a relatively elfin red-tailed hawk chick! It seemed about half the eaglets’ measurement, but everybody appeared to get alongside. At one level, an grownup eagle got here in and dropped a big fish within the nest. Everybody dug into the sushi.
By the point that I visited, each eaglets and hawk have been practically totally grown and continuously examined their wings with vigorous flapping. The younger red-tail even made quick hovers and take a look at flights across the capacious aerie. The variations in measurement was placing. or bald eagle weighs about 10 kilos, is over 2.5 ft lengthy, and has a wingspan of eight ft or so. The red-tailed‘s stats: 2.5 kilos, 1.5 ft lengthy, and the wings span about 4 ft.
The million-dollar query is how did the hawk find yourself in an eagle aerie? One idea is that one of many grownup eagles plucked the red-tailed hawk chick from its nest and introduced it again for meals. The hawk miraculously survived the ordeal, and the eagles have been fooled into considering it one in all their very own.

I put little inventory in that clarification. Extra seemingly is {that a} pair of red-tailed hawks tried to applicable the eagle nest for their very own use, solely to have the rightful homeowners seem and reclaim it. By then, the feminine hawk had already laid an egg or eggs, which have been incubated together with the eagle eggs. And voila! Unusual bedfellows.
Fly like an eagle
This isn’t the primary identified prevalence of bald eagles rearing red-tailed hawks. Two occurrences have been documented in British Columbia, and one every in Michigan and Washington State.
Bald eagle chicks are extremely aggressive and identified to have interaction in fratricide – they generally kill one another. Which makes it all of the extra shocking {that a} hawk chick would survive. However red-tailed hawks are very feisty and this one didn’t appear to take guff from his big siblings.
I believe all of them have been hatched about the identical time, in all probability again in mid-March. Each species’ eggs require about the identical incubation interval: 30-35 days. However the hawks mature far sooner and are able to depart the nest after 45 days. Eagle chicks take round three months earlier than they fledge.
Certainly, inside per week of my go to, observers reported the grownup eagles performing aggressively towards their adoptee – apparently, forcing it to take to the air. Raptor youth generally want some prodding to make their first flight.
By now, the younger red-tail is out by itself and hopefully, doing effectively. Its formative weight-reduction plan in all probability had plenty of fish, and it might be attention-grabbing to know if it tries to proceed with that weight-reduction plan.
