Reference excerpt

The National Aviary, located in Pittsburgh, Pennsylvania, is the only independent indoor nonprofit aviary in the United States. The facility is also the country's largest indoor aviary, and the only one accorded honorary "National" status by the United States Congress. The Aviary is home to more than 500 birds, other animals, and reptiles representing more than 150 species. The aviary has been a member of the Association of Zoos and Aquariums (AZA) since 1984.

Location and features

The National Aviary is located at 700 Arch Street on Pittsburgh's Northside, within Allegheny Commons Park in the Allegheny Center neighborhood. The National Aviary offers daily interactive experiences for visitors, including limited-time activities that change seasonally. Guests can watch an African Penguin Feeding at Penguin Point – an indoor/outdoor habitat that offers opportunities for underwater viewing. For a closer experience with African Penguins, guests can step into Penguin Point to hand-feed the colony alongside an Aviary expert during a Penguin Feeding Encounter or opt for a Penguin Encounter (both for additional fees). The Aviary also incorporates daily Tropical Rainforest and Wetlands Feedings, both of which take place inside of those immersive habitats. These regularly scheduled programs are offered alongside additional engaging expert talks, free-flight bird shows, interactive play spaces for kids, and additional encounters that help to create an educational and immersive experience for visitors.

Birds The Aviary is home to more than 500 birds and other animals of more than 150 species, many of which are threatened or endangered in the wild. As a result, the Aviary has many species that are rarely found in other zoos or aviaries, such as Andean condors and the Critically Endangered Vietnam pheasant, which has not been seen in the wild since 2000. Among the most popular residents are Tropical Rainforest inhabitants Sapphira and Jewel, who are vibrant hyacinth macaws, as well as Wookiee the Linnaeus's two-toed sloth.

Conservation

The National Aviary also takes part in Species Survival Plans designed to enhance conservation efforts for species, including the Bali Myna (nearly Extinct in the Wild), the Extinct in the Wild Guam kingfisher, the Vietnam Pheasant, and the Critically Endangered African penguin. These accredited SSP programs seek to maintain genetic viability and population growth. The Aviary's first two African penguin chicks hatched in February 2012. Since this inaugural hatching, the National Aviary has welcomed more than a dozen African Penguin chicks, leading to its leadership role of the Saving Animals From Extinction (SAFE) program for the African Penguin, an AZA-led initiative to address the variety of problems wild African penguins are facing. On March 13, 2013, the Aviary celebrated another success of its breeding program when a female Eurasian owlet hatched and within five days, doubled in size. Since this first owlet, the National Aviary has expanded its Eurasian Eagle-Owl conservation efforts, including the hatching of more than a dozen chicks. The National Aviary not only hatches species for population growth, they also work with various collaborators to on decades-long initiatives to bring said populations into the wild. In 2019, the Guam rail was downgraded by the International Union for Conservation of Nature (IUCN) from Extinct in the Wild status to Critically Endangered. This is only the second-ever bird species to receive a downlisting, behind the California condor. As of 2020, more Guam Rails have been hatched at the National Aviary than at any other North American zoo. One species that could be downgraded next: the Guam kingfisher. In 2024, nine Guam kingfishers (known by the Chamoru people as sihek) were released into the wild on Palmyra Atoll as part of the Sihek Recovery Program. Three of these birds hatched at the National Aviary – marking the first time a small population of this species has lived in the wild since 1988. More releases of this Extinct-in-the-Wild species are planned for 2025.

History and funding The National Aviary began as part of the Pittsburgh Aviary-Conservatory, built by the city in 1952 on the site of the former North Side Conservatory. Initially consisting of a single structure of 3,640 square feet, a 1967 expansion increased space to 25,000 square feet, including the "wetlands room". Pittsburgh's dwindling urban tax base forced the city to cease funding the institution in 1991.

Public to private In 1991, neighborhood leaders founded Save the Aviary, Inc. and began a public campaign to raise money and develop a plan to privatize the Aviary. Jill Sims, an active volunteer at the Aviary, became the first chairperson of the organization. Mark P. Masterson, a Northside community leader, developed a business plan and secured funding from the Buhl Foundation to produce a capital improvement plan and recruited additional board members. Save the Aviary, Inc. took over the facility and began operations soon after the board of directors hired Dayton Baker as executive director.

National status On October 27, 1993, by declaration of the U.S. Congress, the Pittsburgh Aviary was designated an honorary national status and renamed the National Aviary in Pittsburgh. This was later signed by President Bill Clinton on November 8, 1993. A capital campaign was undertaken in 1995 to raise funds for essential renovations, completed in 1997, that modernized the facility. In January 2005, the National Aviary created the Department of Conservation and Field Research, which so far has mainly focused on restoring bird populations in foreign countries with histories of extreme environmental degradation. In July 2006, the Commonwealth of Pennsylvania granted the first $500,000 toward a $22.5 million project that would include a new education center and expanded exhibits, which was slated for opening in 2008. In October 2008, the Aviary announced a $23 million renovation and expansion of exhibition space, the vast majority of which would be paid for by private foundations.

Worked examples

Example 1 — a first encounter with National Aviary

Start with the simplest possible case. Write down what National Aviary claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Aviary before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Aviary ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Aviary

In research: National Aviary appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses National Aviary in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: National Aviary is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 establishments in Pennsylvania, Aviaries in the United States, Bird conservation, so understanding it makes those chapters shorter.
In everyday life: Look for National Aviary outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
