SACRAMENTO, CA (KTXL/CNN) – When the sun goes down over the Sacramento River, the skunks come out of hiding.
And let’s just say, love is in the air.
Skunk mating season normally peaks after Valentine’s Day (are you listening Pepé Le Pew?), but because of the unusually warm winter weather, the annual ritual may be off to an early start, according to wildlife experts.

PESCADERO >> The first thing you notice is the sound, as you approach the beach at Año Nuevo State Park during the peak of elephant seal breeding season.

To an untrained ear, it's a din of honking, bleating, farting, screeching and wailing.

But to northern elephant seal enthusiasts, it's a symphony of voices, a purpose for each call - the most distinctive of which is the 2-ton bull's throbbing drumbeat of a roar.

As part of the Center for Biological Diversity's "Pillow Talk" program, hundreds of condoms will be distributed for free during Valentine's Day events.

Whether it’s with smooth dance moves or beautiful plumage, males go the extra mile to look good for females.

Hi everyone,
It's back! The City Nature Challenge is on again, this year from April 27-30. It started off in 2016 as San Francisco vs. Los Angeles, last year it was between 16 cities in the US, and this year there are over 50 cities around the world competing! You can see who's participating this year & read more about the challenge at the City Nature Challenge website.
The timeline for the City Nature Challenge is:
April 27-30: Making observations. The project won't accept any observations made before 12:00am on April 27 or made after 11:59pm on April 30.

May 1-3: Getting everything uploaded and identified! As long as the observations were made in the April 27-30 time frame, you can still upload them afterward. Also, the more observations we get identified to species, the higher our species count will be!

May 4: Results announced!
The "big 3" stats that we look at for the City Nature Challenge are (1) number of observations, (2) number of species, and (3) number of people who participated. This year we'll also be putting more emphasis on those numbers with verifiable (not captive/cultivated, and has media) observations.
