As a scavenger and an omnivorous flight bird, air sacs of the hooded crow were the focus of this study. Eight healthy, adult hooded crows were used to examine the morphological characteristics of the air sacs, which were examined grossly and with latex and cast preparations. In general, the morphological overview of the hooded crow air sacs is similar to other avian species. We observed nine air sacs; four paired sacs (cervical, cranial thoracic, caudal thoracic and abdominal air sacs) and one unpaired sac; the clavicular air sac. The cervical air sac communicated to the lung through the medioventral bronchus and had three diverticula; intermuscular, subscapular and subcutaneous. The clavicular air sac communicated with lung through the medioventral bronchus and had subscapular, axillary, humeral, subpectoral and sternal diverticula. The cranial and caudal thoracic air sacs were communicated with lung through the lateroventral bronchi and the both sacs did not have any diverticula. The abdominal air sacs were posterior to the caudal thoracic air sacs. The left abdominal sac was the largest air sac. The right and left abdominal sacs gave off branches to diverticula that pneumatized synsacrum. The abdominal air sacs gave off femoral diverticula behind the hip joint as well as perirenal diverticula.<\/jats:p>","DOI":"10.1111\/ahe.12504","type":"journal-article","created":{"date-parts":[[2019,10,16]],"date-time":"2019-10-16T05:31:22Z","timestamp":1571203882000},"page":"159-166","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Gross morphological features of the air sacs of the hooded crow (<i>Corvus cornix<\/i>)"],"prefix":"10.1111","volume":"49","author":[{"given":"Ahmed K.","family":"El\u2010Sayed","sequence":"first","affiliation":[{"name":"Department of Anatomy and Embryology Faculty of Veterinary Medicine Suez Canal University Ismailia Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9070-9678","authenticated-orcid":false,"given":"Said","family":"Hassan","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Embryology Faculty of Veterinary Medicine Suez Canal University Ismailia Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,10,15]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.1973.tb05063.x"},{"key":"e_1_2_8_3_1","volume-title":"Handbook of avian anatomy: Nomina anatomica avium","author":"Baumel J.
