The overall aim was to detect any signs of aversive responses to this noise to enable keepers to recognize these and take any necessary mitigating actions during the construction period. The experimental approach involved the creation of acoustic maps of each focal animal enclosure, a series of 90-min video recordings of the animals\u2019 behavior in response to ambient noise (control) and amplified broadcast of pre-recorded continuous and intermittent construction noise. Concentration of fecal corticosterone metabolites was also measured for the emus. Key findings were that giraffes, elephants and emus appeared to show an increase in behaviors that could indicate stress or agitation including vigilance and locomotion and may prefer quieter regions of their enclosure during sound exposure. Giraffes also increased close contact with conspecifics when exposed to construction noise. While alligators did not show clear evidence of noise-related stress, our findings indicated that all focal species showed some behavioral responses to recorded construction noise.<\/jats:p>","DOI":"10.3390\/ani9080504","type":"journal-article","created":{"date-parts":[[2019,7,31]],"date-time":"2019-07-31T11:37:07Z","timestamp":1564573027000},"page":"504","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Potential Impact of Construction Noise on Selected Zoo Animals"],"prefix":"10.3390","volume":"9","author":[{"given":"Richard","family":"Jakob-Hoff","sequence":"first","affiliation":[{"name":"New Zealand Centre for Conservation Medicine, Auckland Zoo, Auckland 1022, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4265-5307","authenticated-orcid":false,"given":"Michael","family":"Kingan","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Auckland, Auckland 1010, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9248-713X","authenticated-orcid":false,"given":"Chiaki","family":"Fenemore","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Auckland, Auckland 1010, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gian","family":"Schmid","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Auckland, Auckland 1010, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5239-6591","authenticated-orcid":false,"given":"John F.","family":"Cockrem","sequence":"additional","affiliation":[{"name":"School of Veterinary Science, Massey University, Palmerston North 4442, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda","family":"Crackle","sequence":"additional","affiliation":[{"name":"New Zealand Centre for Conservation Medicine, Auckland Zoo, Auckland 1022, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Van Bemmel","sequence":"additional","affiliation":[{"name":"School of Environmental and Animal Sciences, Unitec Institute of Technology, Auckland 1142, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Connor","sequence":"additional","affiliation":[{"name":"School of Environmental and Animal Sciences, Unitec Institute of Technology, Auckland 1142, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kris","family":"Descovich","sequence":"additional","affiliation":[{"name":"School of Environmental and Animal Sciences, Unitec Institute of Technology, Auckland 1142, New Zealand"},{"name":"Centre for Animal Welfare and Ethics, School of Veterinary Science, University of Queensland, Gatton, QLD 4343, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mellor, D.J.
