J51 was with mom and J47 (J19 and J35 were nearby), and there did appear to be some pushing going on. A few times J47 surfaced right with J51 while J41 was a little bit ahead.
J47 was breaching a bit as well, it was pretty charming and interesting to see him tagging along with the baby.
I’m not sure if this photo is the baby getting a little bump or him skirting out of the water sideways (I think it is the latter as none of the other photos clearly shows another whale under him). Maybe I should know better than to poke the raging hornet’s nest that is SRKW gossip but …. looks like J51 is a male.
