Ongoing Expansion Threatens Chimneys for Urban Swifts

Property Acquisition Continues on Northeast Creighton University Campus

James Ed. Ducey

Acquisition of additional properties for the ongoing expansion of Creighton University will mean the further ruination of chimneys useful for breeding and migratory swifts.

The northeast portion of the campus and adjacent properties in North Downtown have a number of buildings with chimneys in the older buildings. A number of these on several city blocks - 16 individual parcels - are being acquired by Creighton University from Modern Equipment Company. The property will be used, possibly according to the campus master plan showing athletic fields southwest of 17th and Cuming Street. Student residences are shown on other portions of the purchased parcels.

An additional consideration is the ongoing discussion for a north downtown ballpark near 16th and Cuming Streets. This will mean removal of all buildings present on that tract. Other developments have altered the area, with new constructions of buildings - without chimneys - for the trendy NoDo.

Several chimneys used by swifts will eventually be removed from the area of the announced Creighton acquisitions. The parcel on the north side of the 2000 block of Cuming Street is being suggested for economic development as retail, service or residential use.

Area B will be a ball field. Note the buildings recently demolished for the soccer complex now southwest of 17th and Webster streets.

During autumn surveys to record migratory birds, special scrutiny was given to these city blocks and to evaluate the status and features of its chimneys. The first few visits to this area were in the autumn of 2003 (Ducey 2003). Autumn 2005 research surveys were various intervals from 6-13 September.

Information on the buildings with chimneys includes street address, with parcel ownership and building date (usually) from the Douglas County Assessor's website. Other notes are based on the surveys or information from Creighton University.

Chimney List

There are many chimneys for the buildings of the area. The structures date to 1883, 1886, from the 1890s to 1920s and to 1949 and 1951. Smaller chimneys get used by breeding swifts, while larger sizes are roosts for local and migratory flocks. Those chimneys noted to be suitable for swifts are generally 2x2.5 bricks or larger, based on an evaluation of more than 90 chimneys in Lincoln during seasonal breeding.

14 chimneys

There are more than 30 chimneys of interest as swift habitat in North Downtown (see figure). The structures are scattered about the area at a variety of buildings of different age and condition. Since the 1880s when the first buildings were erected, there have been many decades, and likely more than a century of annual use of distinct chimneys by breeding and roosting swifts.

The oldest buildings noted in the area are dated to 1880, 1883 and 1886. If the chimneys at these locales are used by swifts, it would make them the oldest known structures used by swifts in Omaha.

Buildings owned by Creighton University account for most of the total. This number would have been greater in the recent past, but with ongoing expansion, buildings and their chimneys are being demolished. The oldest known building in the area - from 1880 - is university property with chimney apparently large enough, and probably suitable for breeding swifts.

New construction will remove additional properties in the long term, about 10-12 years according to an official in the university facilities department.

Expansion that University officials had previously said would occur in several years, has moved ahead. Further expansion can occur as new parcels are being acquired.

Regarding 723 North 18th Street, redevelopment would occur in several years. There were no current plans for the building at 1913 Cuming Street - dating to 1890. The place is in poor condition, including the east wall next to the roost chimney that is splitting away from the remainder of the structure. There were no plans for the University properties along 16th street, and these may be sold, according to the facilities official comments three years ago.

Elsewhere on campus, Creighton medical Center expansion meant a bunch of buildings were also removed to make way for a parking lot north of California Street and west of 30th Street. One house remains, with a small sized-chimney.

Other buildings also have a tenuous future. A second building from 1880 sits empty, and has a smaller sized chimney that may be suited for nesting swifts. At 816 Florence Boulevard, a very small, unused building sits empty on a prime corner lot within the projected campus area. Other places appear they are not used and await a new property future, one without regard to any importance of the chimney to resident birdlife.

While university and city officials promote development of the area for students and pedestrians, and feature outdoor events, there is a reduction in a key aspect of the community. There is no regard to the chimney dwelling birds which each day during the summer season eat a myriad of insect pests, improving the scene for people.

Nearly two-thirds - the majority - of the chimneys noted will be gone in the long-term, causing a dramatic decline in suitable places for swifts.

This urban setting has a continuing decline in habitat structures, with no mitigation for losses caused by demolition of buildings. Efforts are needed to provide replacement nesting towers and to conserve present chimneys where feasible to ensure representative sites featured at older buildings are maintained.

The trend for swifts, because of changes underway, indicates that these bugeaters habitat will severely decline in an area where they are now regularly so common in autumn. Habitat loss will cause a decline in their community status during the breeding season. Chimney Swifts migrating southward along the Missouri Valley will have fewer options for finding a safe haven for the night.

This north Omaha portion of the city is integral with the mix of the chimney swift's occurrence in other parts of this city, which is such an interesting place to study swift habits.
