Hi, new member here from Northern Territory (NT) Darwin.
I'm interested to know more about the species and differences of birds that frequently visit my backyard and others that aren't so frequent. If anyone would like to put in a bit of advice on identification, you would be welcome! I'd be interested to chat with anyone that could help. What I'm really wanting to know is, what are the most obvious differences between female and male bird species? Or does it vary too much to say?
Thanks in advance!
Hi Olivia welcome to the site,
This is a great site to meet people with common interests and who can help you out with all your identification needs. In general the main differences between male and female is that the males are more brilliantly patterned and coloured however this is a generalisation. The main way to improve your identification skills is to get a field guide and do lots of birdwatching
.
Hope to hear from you more and hope you enjoy the site.
Cheers BabyBirdwatcher

The males are usually more colorful then the females but there are exceptions especially in the parrot family, sometimes the female can be just as colouful as the male and maybe even more beautiful, in some cases it's impossible to know by sight and that's when DNA is useful, hope this helps a little, cheers.
For Australian birds, natives=life, exotics=death, so do them a favour and go plant some natives and save their lives.
Discerning the difference between male and female gets even harder (in some species) depending on age too i.e. if the birds are juveniles or fledglings. Actually, if they're juveniles etc, they can look totally different to the adult they will become for some, so it can be sometimes difficult to even tell then which species they are, never mind if they're a boy or girl, well for me anyway
. A warm welcome to the site! Look forward to hearing and seeing more from you down the track!
