Comparison of fecal glucocorticoid metabolite concentrations in hand‐ versus parent‐reared whooping cranes (Grus americana)
Endangered whooping cranes (Grus americana) have been produced in captivity for reintroduction programs since the 1980s, using techniques such as artificial insemination, multiple clutching, and captive‐rearing to speed recovery efforts. Chicks are often hand‐reared (HR) by caretakers in crane costu...

| description | Endangered whooping cranes (Grus americana) have been produced in captivity for reintroduction programs since the 1980s, using techniques such as artificial insemination, multiple clutching, and captive‐rearing to speed recovery efforts. Chicks are often hand‐reared (HR) by caretakers in crane costumes, socialized into groups and released together, unlike parent‐reared (PR) cranes that are raised individually by a male/female crane pair and released singly. HR cranes historically exhibit greater morbidity rates during development than PR cranes, involving musculoskeletal and respiratory system disease, among others. We hypothesized that HR crane chicks exhibit a higher baseline fecal glucocorticoid metabolite (FGM) concentrations during the development compared with PR chicks. Fecal samples were collected between 15 and 70 days of age from HR (n = 15) and PR (n = 8) chicks to test for differences in FGM concentrations using a radioimmunoassay technique following ethanol extraction for steroids. Linear mixed model analysis suggests increasing age of the chick was associated with an increase in FGM (p |

HIGHLIGHTS
Rearing strategy affects fecal glucocorticoid metabolite production in young whooping cranes.
Glucocorticoid production in whooping cranes varies by individual, by age, and by sex.
Early exposure to higher glucocorticoid concentrations may benefit future survival.</description><identifier>ISSN: 0733-3188</identifier><identifier>EISSN: 1098-2361</identifier><identifier>DOI: 10.1002/zoo.21541</identifier><identifier>PMID: 32270553</identifier><language>eng</language><publisher>United States: Wiley Subscription Services, Inc</publisher><subject>Age ; Aging ; Animal Husbandry - methods ; Animals ; Artificial insemination ; Birds - metabolism ; captive‐rearing ; Captivity ; Chickens ; Chicks ; corticosterone ; development ; Endangered Species ; Ethanol ; Feces ; Feces - chemistry ; Female ; Females ; Glucocorticoids ; Glucocorticoids - chemistry ; Glucocorticoids - metabolism ; Grus americana ; Humans ; Juveniles ; Male ; Metabolites ; Morbidity ; Physiology ; Radioimmunoassay ; Reintroduction ; Reproduction (biology) ; Respiratory system ; Sex ; Steroid hormones ; Steroids ; Strategy ; whooping cranes</subject><ispartof>Zoo biology, 2020-07, Vol.39 (4), p.276-280</ispartof><rights>2020 Wiley Periodicals, Inc.</rights><rights>2020 Wiley Periodicals LLC</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c3131-ec4caa2667b711c0ee36410bef18190740a9736598ea423bde3d98bce57437af3</cites><orcidid>0000-0002-7437-0157</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fzoo.21541$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fzoo.21541$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,776,780,1411,27901,27902,45550,45551</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/32270553$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Brown, Megan E.</creatorcontrib><creatorcontrib>Torkelson, Miranda R.</creatorcontrib><creatorcontrib>Olsen, Glenn H.</creatorcontrib><creatorcontrib>Krisp, Ashley</creatorcontrib><creatorcontrib>Hartup, Barry K.</creatorcontrib><title>Comparison of fecal glucocorticoid metabolite concentrations in hand‐ versus parent‐reared whooping cranes (Grus americana)</title><title>Zoo biology</title><addtitle>Zoo Biol</addtitle><description>Endangered whooping cranes (Grus americana) have been produced in captivity for reintroduction programs since the 1980s, using techniques such as artificial insemination, multiple clutching, and captive‐rearing to speed recovery efforts.
