Ok time to weigh in on this one. The actual answer is
e) All of the above
And I'm not just saying that to appease everyone. When designing the logo we went through literally dozens of concepts with the designer, Plunge -
www.plunge.com.au if anyone is interested, an amazing design group - and there was something about the birds that really stood out.
Same Same is a community site and the way birds congregrate and flock together is really unique. Zakalwe is correct is saying they are hummingbirds, and traditionally hummingbirds represent people being close (I'm not going to say love here, because that's naff, but there's an element of the birds being close to each other and interacting).
Same Same itself means lots of different things, we all share some of the "same same" things deep down (ie, our sexuality), but we're all very different in expressing that. By having the "same" bird, but with two different colours it goes some way in conveying that idea.
So that's the story behind the logo: it is intentionally vague and open to interpretation, and that's exactly why we love it!
