Today I spotted a couple of interlopers in an area that’s the regular hangout for a group of Crested Pigeons. One of the interlopers looks like a regular Spotted Turtle-Dove. Here’s a Crested Pigeon on the left and the interloper on the right:

But nearby, on the same wire, is this rather interesting individual:

The bird looks like a Spotted Turtle-Dove but has a bit of feathery decoration on its head. Could it be a cross-breeding of a Spotted Turtle-Dove with a Crested Pigeon? Or is it just a Spotted Turtle-Dove having a bad hair day?

Here’s another pic of the same Crested Pigeon as in the first photo:

Crested Pigeons are native to Australia. When they take off, you hear the distinctive whistling noise from their wings that is characteristic of many pigeon types. When I first saw these birds, I thought how typical it is that even the common pigeons in Australia are different from those I’ve seen in other part of the world.

The group of birds later moved down to forage on the ground. Here’s one of the Crested Pigeons:

There was only one bird that looked like a Spotted Turtle-Dove with a vestigial crest. Here’s another pic of the same bird:

Spotted Turtle-Doves are not native to Australia. They were introduced in the late 1800s, and are seen as a pest in some regions of the country.

Pigeon or dove? The names “Crested Pigeon” and “Spotted Turtle-Dove” led me to wondering, not for the first time, what the difference is between a pigeon and a dove. I’ve asked various people over the years. Some say doves are white whereas pigeons are not. Other say that doves are smaller than pigeons. According to much of the internet, the two terms are interchangeable.

Here’s another view of the same bird with the miniscule crest (or perhaps it’s just a feather expressing its individual identity):

A wink, almost as if the bird knows that it’s presented me with a puzzle:
