4/19/09 - TNC Waikamoi Preserve, East Maui (1 Viewer)

We were given a tour of the public trail in the Nature Conservancy's and Haleakala Ranch's Waikamoi preserve on the North slope of East Maui. The weather was absolutely perfect.

The "Hosmer's Grove" area was a bit of a shock. The trail was extremely short. There has been little/no attempt to replace the alien trees with native species. There were plenty of the common native birds, though, and it was odd to see native birds in alien trees that they usually ignore on Hawai'i. Not what we came for.

After meeting our guide and walking WAY down through the alien tree plantation we finally arrived at the edge of the native forest and the Waikamoi boardwalk. The forest is mesic, not rainforest, and contained only the most common native plant species. I had been hoping for rare and interesting Maui plants, but it was much like the upper Saddle forests. We stayed near the end of the boardwalk, accumulating birds. When we got there we saw plenty of Maui 'alauahio (creeper), which may be the most attractive of the remaining honeycreepers. Very bright and much like an American warbler. In less than an hour we started to see 'akohekohe. Maybe 8 total today. Maui parrotbill (pocket 'akiapola'au) soon followed, with 4 encounters, but possibly all the same bird. All 3 made very distinctive sounds that allowed us to search for them effectively. We stayed for a few hours trying to get better photos, with partial success. Too bad we only had one day and could not leave the boardwalk area.

Photos are in the next entry....
 
Was this a standard NPS/TNC tour, or something special? I'll be on the standard tour next week Thursday, and I would consider myself lucky to find 'akohehoke, much less the parrotbill.
 
The national park cancelled all their tours this weekend, so we arranged to go with conservation staff. This worked out well, because we were able to go out with someone who knows the Maui bird calls really well and stay out there all day and learn a lot. I'm hoping to help them with scouting and surveys sometime in the future.

Here is the scoop on the tours. First, they're often cancelled! There are two tours. The "short" tour only goes to a big gulch where some native trees remain along the gulch walls among the vast wasteland of conifer plantations. People who are really interested in scenery more than native stuff will prefer this one. I highly doubt parrotbill or 'akohekohe are seen on that tour. The better tour is the boardwalk tour, which just gets into the upper edge of the native forest. We spent the day on the platform at the end of the boardwalk and saw both of the endangereds there. You want to be on the boardwalk tour if possible, and tell them that you'd like to spend as much time at the end of the boardwalk as possible to have a chance to at least hear the endangered birds. (and enjoy plenty of 'alauahio)

As always, knowing what the birds sound like is the key to finding them. The 'akohekohe were very difficult to hear. They made a quiet throaty "aaarp-aaarp" sound that didn't carry well. They also fly a little different than 'apapane - less fluttering and more undulating and direct flight without wing whir. They're primarily at the tops of trees, and seem to like to call from the tops of dead snags. The parrotbill are much louder. They have some short calls, and then the male sings the distinctive "chewEE-chewEE-chewEE-chewEE...". However, they sometimes talk with the 'amakihi, causing confusion. Fortunately a male frequently returned to the boardwalk while we were there. It is hard to see far from the boardwalk, so even when you hear them a lot of searching may be required.
