It’s a variant of [name]Muriel[/name] and reminds me of [name]Merle[/name] [name]Oberon[/name] so it sounds feminine to me.
I like the sound, the meaning and the blackbird association. I think it would be perfect for a little girl born in winter, but it was more used as masculine name in the past and I’m not fond (understatement) of unisex names.
[name]How[/name] do you feel about this name? [name]Do[/name] you think it would suit more a boy or a girl?
Sorry for the bad English 
It’s definitely a girl’s name for me, and actually, I’ve never thought of it or heard of it for a boy (beautiful name in my opinion)
I would say neutral. I love it for either gender, and I love that it’s truly unisex.
First thing that comes to mind is [name]Merle[/name] Haggard (male country music singer). I don’t think I’m feeling it for a girl. Or a boy, really.
I know two [name]Merle[/name]'s, both male. But I think I might like it better for a girl.
I think boy right away, and in fact I didn’t know it was a girl’s name at all. It’s not my style for either gender, but I suggest [name]Merel[/name], which has the same beautiful “blackbird” meaning and looks all girl. I think [name]Muriel[/name] and the variant [name]Meriel[/name] are sweet too.
It’s male in my opinion.
Girl. I’ve heard of it being used on a boy.
It sounds more masculine to me, probably because it rhymes with “[name]Earl[/name]”.
Also it’s the name of a really skeevy male character on The Walking Dead.
I’ve never seen it used on a girl. All boy to me. Well, more old man than boy, but I definitely think male.
I only know it for a girl
I would say either, [name]Merle[/name] [name]Oberon[/name] like you said is a girl, [name]Merle[/name] Haggard who was mentioned is male so I think people can associate it with both.
[name]Both[/name]. I could see it on either gender. I think I like it more for a boy, but would be fine with it on a girl.
I had a great uncle [name]Merle[/name] so I will forever associate it with old men
It sounds more masculine to me. I didn’t know it could be used as a girl’s name, but from the previous comments it looks like people are split enough that it could probably go either way.
To me it’s more feminine.
[name]Merle[/name] = male (and it means ‘blackbird’ in French)
[name]Muriel[/name], [name]Meriel[/name], [name]Meryl[/name] = female (Irish for “shining sea”)
If only ever met girls named [name]Merle[/name], and I never knew it could be a boys name.
When I first saw your post, I thought of it as a girl’s name (rhymes with [name]Pearl[/name]?) & I like the sound of it 
What part of the world are you living in? That would be a huge factor in whether this name would work for you and whether it would be associated with any of the Merles mentioned in pp (of whom I’ve never heard of before today)
In French, yes, merle noir means blackbird, merle bleu is bluebird etc. [name]Merle[/name] refers to quite a few bird species. It’s also the word used to describe the mottled colouring of certain dog breeds, it’s the French word for a species of fish, it’s also a place name and a family name… type in “merle” in the French Wikipedia page and you will see the longish list of all things [name]Merle[/name]
Although I like the name and its bird association, based on all the other posts and that you said you hate unisex names, it sounds like you should steer clear of this one. I like the pp suggestion of [name]Merel[/name].
Oh, and your English (in this post) is just as good as anyone else’!
I immediately think feminine, but like many nature names it could go either way. I’m actually surprised to see it mentioned so many times by PP as an old man’s name. Based on previous replies, it definitely leans toward unisex, because on a boy it sounds feminine to some, and on a girl there are those who would see it as a geezer name.
