I’ve visited the National Aquarium in Baltimore, Maryland, twice in my life, as soon as in my youth and the opposite as a school scholar. One of the numerous issues that impressed me was the vary of the animals.” Our rainforest exhibit accommodates a pleasant assortment of soft-billed birds and we now have taken the chance to carry these birds heart stage,” mentioned Ken Howell, the curator of rain forest displays on the National Aquarium.
With a rising curiosity in managing smaller passerine birds in a extra sustainable method the National Aquarium has had appreciable success with lots of the species. Howell has been on the Aquarium for the previous decade and contributes the success on the expert and enthusiastic staff of aviculturists and their potential to drawback remedy.” It will be tough to take care of and [breed] a number of hen species inside a walkthrough exhibit that additionally accommodates golden lion tamarins, two-toed sloths, fish, amphibians and many human guests.”
Howell has working with animals his complete life and appreciates all species from spiders to hippos. With persistence and a little bit of luck, he admits, he was capable of break in to the zoo enterprise a few years in the past.” There is a lot to find out about dwelling collections, and the people who take care of them, and I discover that even after 35 years within the enterprise I’m nonetheless actively studying,” he defined.
Birds will be seen on the Aquarium within the Upland Rainforest, Sea Cliffs and Australian displays. The Animal Programs part additionally accommodates a small variety of birds which might be utilized in public displays.
The rainforest part homes greater than a dozen species of birds and in addition manages the Sea Cliffs exhibit which accommodates Atlantic Puffins, Razorbills and Black Guillemots.
Meet Screaming Pihas
“I am very fond of our Screaming Pihas,” Howell mentioned. Although widespread all through a lot of South America they proceed to stay uncommon at zoos. The Aquarium presently has one pair. “The male piha amazes everyone with his loud unique whistle like call. Surprisingly, very little is known about screaming piha biology and there is only a smattering of information on other piha species.”
The feminine on exhibit started developing a nest a few years in the past and the workers put all the knowledge they gained into impact. Howell tells me that it’s a slight exaggeration as the feminine piha makes an extremely tiny and poorly-constructed platform on which to put her egg.
Ornithologist, Alexander Skutch as soon as described a piha nest as being “the most meager arboreal nest that I had seen, this unbelievably slight structure seemed to contain the irreducible minimum of material that would suffice to support an egg in the air.”
The feminine’s nest on the National Aquarium is not any completely different. “[It’s] only 2 inches long by 1.5 inches wide and is constructed of curling vines,” Howell describes. “Rainforest aviculturists, uncomfortable with the design of the nest, inserted one or two additional twigs to provide greater support to the structure.”
With male pihas taking part in no position in nest constructing, incubation, or caring for the younger the workers thought they might give the feminine a lift with nest constructing.
With a little bit of luck the workers was capable of see a single egg. “Light brown in color, it was perfectly camouflaged,” Howell recalled. “The female piha was acutely aware of and uncomfortable with anyone watching her and we spent only short periods of time examining her on the nest.”
What is much more exceptional is that the nest constructing, egg laying, and chick rearing all befell eight toes or much less from the rainforest walkway the place hundreds of summer season guests had been strolling.
With earlier work in rearing small birds in thoughts the workers launched stay silkworms into the piha eating regimen. Once the egg hatched, the feminine preferentially fed silkworms to the chick. Since the feminine piha should go away the nest to eat and collect meals for her chick single parenting is tough.
“The piha chick relies completely on camouflage to remain safe in the nest when the mother is absent,” Howell says. “Remaining motionless, laying ventral side down with wings drooped at its side, and with eyes closed, the chick gives no indication that it is even alive.”
One of the rainforest aviculturists excitedly commented, “I think I saw it breathe.” Piha chicks don’t peep, hole or beg, all issues we historically affiliate with child birds. This is to maintain their location cryptic.
“The mother returns to the nest with food and taps the chick” beak which shortly opens, engulfs the meals, and simply as shortly closes once more,” Howell mentioned. “While the chick of the cinnamon-vented piha is described as resembling a hairy caterpillar complete with orange spines, our screaming piha chick resembled an odd gray grub that was as big as the nest upon which it laid.”
The piha mom was a wonderful mom, with the chick fledging. This marked the second rearing of a screaming piha in captivity and the primary in North America. “Quite remarkable,” Howell says.
You can meet a variety of birds within the National Aquarium’s Upland Rainforest exhibit.
Within the final couple of months the Aquarium has efficiently hatched and fledged turquoise tanagers, silver-beaked tanagers, red-capped cardinals, and blue-crowned motmots. Even newer is the hatching of two Atlantic puffins. All of those species are managed throughout the AZA Species Survival Programs.
The National Aquarium is positioned at Baltimore’s Inner Harbor providing much more after you go to the services distinctive assortment dwelling in effectively planted fertile displays.
