The executive director shall serve as a non-voting member of council and the executive committee.”
“The aos has members who pay annual dues.”
“The aos members elect a council and officers; council meets three to four times a year to address governance issues.”
“The aos audit committee reviews and approves the 990 prior to submission. The 990 is distributed to aos council and is also made available through the society website, americanornithology.org, as well as upon request.”
“Aos officers, council members, and employees annually submit a conflict of interest disclosure statement as a requirement for their service to, or employment with, the society. Potential conflicts are recorded and monitored by the executive director in consultation with the secretary of the society.”
“The executive compensation policy authorizes the executive committee of the council to conduct the executive director's annual appraisal, and to recommend to council executive compensation and benefits. The policy requires a compensation study to be performed periodically; a study conducted in fy2018 was used to inform compensation for 2019.”
“Governing documents, policies and financial statements are available upon request and on the website.”
“To provide grants for research and education in the field of ornithology.”
“Aos is exempt from federal income taxes under section 501(c)(3) of the internal revenue code except for any unrelated business income. Aos has adopted the requirements for accounting for uncertain tax positions and management has determined that aos was not required to record a liability related to uncertain tax positions as of december 31, 2019.”
