Dear MARMAM, My co-authors and I are pleased to announce a new paper on blue/fin whale hybrids: Sightings and Satellite Tracking of aBlue/Fin Whale Hybrid in its Wintering and Summering Ranges in the EasternNorth Pacific Jefferson, Thomas A;Palacios, Daniel M; Calambokidis, John; Baker, C. Scott;Hayslip, Craig E; Jones, Paul A; Lagerquist, Barbara A;Jørgensen, Morten; and Schulman-Janiger, Alisa AbstractWe report 20 photo-documented sightingsof a blue/fin whale hybrid between 2004 and 2020, in its wintering andsummering ranges in the Gulf of California, Mexico, and southern California,USA, respectively. The whale wasconfirmed to be a hybrid by genetic testing using a reference dataset ofnon-hybrid blue and fin whales. It was also tracked by satellite for 28 days in2015, showing its feeding range extended to the Big Sur area of centralCalifornia. Information is presented toassist in field identification of blue/fin whale hybrids. The paper is available for open-access download:@font-face {font-family:Times; panose-1:2 0 5 0 0 0 0 0 0 0; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 0 0 0 1 0;}@font-face {font-family:Times; panose-1:2 0 5 0 0 0 0 0 0 0; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 0 0 0 1 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-520092929 1073786111 9 0 415 0;}@font-face {font-family:Cambria; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1073743103 0 0 415 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin-top:0in; margin-right:0in; margin-bottom:10.0pt; margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:Calibri; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}span.lrzxr {mso-style-name:lrzxr; mso-style-unhide:no;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:11.0pt; mso-ansi-font-size:11.0pt; mso-bidi-font-size:11.0pt; font-family:Calibri; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}.MsoPapDefault {mso-style-type:export-only; margin-bottom:10.0pt; line-height:115%;}div.WordSection1 {page:WordSection1;} https://irispublishers.com/aomb/pdf/AOMB.MS.ID.000545.pdf Best wishes,Tom JeffersonClymene Enterprises
