 This bird is easily recognized it by it's size (at a length of 22-26 inches, it's fairly big) as well as by it's posture and location. They are often seen hunched down on the edge of a water source looking for prey.

Those who live near town in Honolulu can see them often along the Ala wai canal near Ala Moana beach park. These herons leave feeding areas near dusk to fly back to nest colonies high in trees. Sometimes, several nests can occupy a single tree.

Native Species of the Week: Hawaiian monk seal

What's that in the tidepool? A fish? A shark?

It's an endangered Hawaiian monk seal!

These monk seals were spotted at Kaena Point Natural Area Reserve on the island of Oahu. Hawaiian monk seals are native to Hawaii, and they are endemic, meaning they are found no place else in the world. This is their only home.

Monk seals love to relax and recharge in the tidepools, and can often be seen here, at the Western-most point of Oahu.

Monk seals used to live throughout the Hawaiian archipelago, and along with the Hawaiian Bat, is one of only two native mammals that live in the islands.

The Hawaiian name for monk seal is 'īlio-holo-i-ka-uaua, and translates into English roughly as "dog running in the toughness," which probably refers both to it's doglike face and it's awkward way of moving on land.

To learn more about monk seals, visit the NOAA Pacific Islands Fisheries Science Center page.

Other animals you may see at Kaena include Laysan Albatross and Humpback whales
, depending on the season.

If you visit Kaena Point, make sure to respect all posted signs within the Natural Area Reserve, and be prepared! (See below for guidelines)

Keep an eye out for the monk seals, but make sure to observe them from a distance. Bring your binoculars and zoom-lens camera, and you'll be able to watch these endangered animals play and lounge in the shallows.
Some guidelines for visiting this amazing place:
- Be prepared! Bring lots of water. It is usually hot and sunny in this area.
- Wear comfortable clothes, hiking or walking shoes, sunscreen and a hat.
- The hike is 2.5 miles long, and can take up to 3 hours, depending on your pace.
- Be aware of the big waves and strong currents along the coast, and stay away from the water unless you are familiar with these hazardous conditions.

Kaena Point is a favorite spot on Oahu for Endangered Hawaiian monk seals, you can help their home be a pleasant place for them and for visitors:
- Leave your pets at home; dogs can disturb or even kill ground-nesting birds.
- Stay on the trails and avoid disturbing the birds.
- Prevent fires and carry out all your rubbish.
- Lend a hand and pick up litter on the ground.
- Leave all living things as you found them.

Native Species of the Week - ‘Ōpe‘ape‘a; Hawaiian Hoary Bat

Hawaiian name: ‘Ōpe‘ape‘a
English name: Hawaiian Hoary Bat
Scientific name: Lasiurus cinereus semotus

Photo: DOFAW

The Hawaiian Hoary Bat is Hawaii's only native terrestrial mammal. It is one of only two native mammals in the entire island chain (the Hawaiian monk seal is the other).

It is an endangered species, and is endemic at the subspecies level, meaning the bat that lives here lives nowhere else in the world.

The bat is brown and gray, and has a wingspan of about 1/3 of a meter, or about 1 foot. This bat has a lot in common with other bat species, but since very little is known about this particular mammal, much more research needs to be done.For example, not very much is known about the habitat requirements or population status of the Hawaiian Hoary Bat. 

" ‘Ōpe‘ape‘a feed on a variety of native and non-native night-flying insects, including moths, beetles, crickets, mosquitoes, and termites; and similar to other insectivorous bats, prey is located using echolocation." -From the Hawaii Comprehensive Wildlife Conservation Strategy webpage.
