Fun fact. The Monarch butterfly migration is one of the longest-known, multi-generational insect migrations on our planet. Every fourth generation lives 8 times longer than the previous generations and travels 10 times farther.

It’s not a straight shot to the far side of the Moon! 🌕 Over approximately 10 days, the Artemis II astronauts will orbit Earth twice before looping around the far side of the Moon in a figure eight and returning home.

Kestrels are basically the hover kings of the bird world! 🛑🕊️ With nothing but their wings and wild skill, they can stay frozen mid-air like nature hit the pause button.

Black skimmers exhibit a trait we could all learn from: persistence. They, like other wildlife never give up and it’s not by choice. They simply can’t. It’s not an option. If they want to survive, they must keep trying over and over again.

Timing is everything, isn’t it? And sometimes being in the right place at the right time feels well, timely, or even predetermined. With wildlife photography, it’s all about being in the right place at the right time. The more you know about your subject, the better because it increases your chances of being where you need to be when you need to be there. There is also an element of just letting go and taking what is given to you. It’s always best to have no expectations at all when it comes to wildlife. On this morning, everything did fall perfectly into place, and I was able to capture this dreamy scene of a beautiful Dalmatian pelican and its reflection on smooth water as it came in for a landing. Oh yeah, the glorious snow-capped mountains in the back were definitely a treat too. The days prior to this, that mountain range was hidden by clouds. I didn’t even know it was there. 🤪
