Not only have I noticed them singing at night, but I have also observed certain species CHANGING their usual vocalizations over the past few years. In
particular, the DOVES in my area are making odd sounds over the past couple of years that I had never heard in the previous DECADES come from them.
Something is indeed going on.
Wow, bird activity coming into ATS forums.... geezus.
2 things here:
FYI, certain species of the dove family have been expanding their ranges northward in North American for several years now (at least a decade).
Possibly due to climate change or other ecological factors (no one knows precisely why... maybe because we need more scientists to go out in the field
and do research!).
If you look at bird field guides published several decades ago, the White-winged Dove (Zenaida asiatica) was formerly a bird of the far southwestern
arid areas of the United States (southern Texas, New Mexico, Arizona, California). Within the past 10-15 years they have expanded their range
northward and are commonplace every-day birds in cities where they were very rarely sighted a decade ago.
The same goes for Eurasian Collared-Doves (Streptopelia decaocto). As with any species on earth, they go through population and range shifts.
Eurasian Collared-Doves gained a foothold in Florida several years ago, and within the last decade+ due to ecological / evolutionary factors their
range has exploded in North America and are common and widespread even to Canada, where they were unheard of just a few years ago.
I have a feeling the person commenting noticing new calls in their local doves is somewhere in the US, where these 2 dove species have greatly
expanded their range in recent years. Yes they have different (although still dove-like) calls from the Mourning Doves and Rock Pigeons you are used
to seeing and hearing. It's not a conspiracy, it's evolution in progress - possibly affected by climate shift, human developments, or just the fact
that the dove family is a highly adaptive modern line of birds that is doing very well these days.
Some birds sing at night. That is just a fact of nature. Northern Mockingbirds are ubiquitous throughout much the the United States, and they do sing
and night, and have done so for thousands of years. Just because your awareness of it is new does not mean the phenomenon is new.
Maybe you are just having problems sleeping at night and so you start to notice the loud (beautifully voiced!) mockingbird singing out of your window
I can understand distrust of our governments, political and financial leaders, etc.
But the more and more I read ATS forums, I get the distinct impression that we (at least ATSers) are relapsing to the dark ages where easily-gained
scientific knowledge is being veiled by laziness to learn, read books, go outside, study nature, study science.
Come on guys, don't be afraid of the mockingbird. If you're worried about them, just go buy some bird books and read up, or go bird-watching. If
you want to worry about something, worry about political and social trends and the religious right spewing crap to hinder scientific awareness.
