Eagles mate 10 months out of the year, strengthening their bond and commitment to each other, but the female is only fertile for about 2+ weeks prior to and during her egg lay period. Her ova are ‘switched on’ by a hormone secreted by her pituitary gland, which is activated by increasing daylight length. They are ‘switched off’ by the hormone prolactin, which is associated with incubation. If copulation was successful during this period, an egg would be fertilized and one or more eggs would be expected. It is generally believed that a successful copulation takes place 5-10 days before an egg is laid.

i made some last minute shopping and while i was driving to the shop and back i had more time to think about this.
the quoted article is about bald eagles, the North-American cousins of our WTEs. they are very special animals because they have sex for fun, for strengthening pair bond, without possibility of producing offspring.
that was once thought to be a human characteristic, but even that was not entirely so (like most of the things that were supposed to be special for us humans). in principle humans have sex all the time
and fertilization is possible at any time (for young human females anyway).
bonobo monkeys (
Pan paniscus) probably have the record in having sex outside of procreation purposes. while we humans shake hands as a greeting bonobos have sex, all bonobos is the group regardless of their sex or age. it's
tsump-tsump for a few times here and there and then they continue their business. i don't know if that is so special anymore, do they climax or anything like that. it may feel like a handshake only.
