Sequiota Cave Boat Tour

/

My daughter enjoyed a boat tour of Sequiota Cave (in Springfield, Missouri’s Sequiota Park) last spring and encouraged us to sign up when they were offered this year. They only do the guided tour a couple of weekends in the spring and fall – leaving the cave to the roosting bats for the rest of the year. The instructions were to ‘bring your own headlamps’ so we grabbed our headlamps that we have for astronomy nights/emergencies.

It was my first visit to the park, and I was a little disappointed that Galloway Creek was dry. It has been channelized in the area near the cave entrance with abutments and concrete additions. There was a bumpy area of concrete that might work to slow the water a bit.

The buds on some of the young trees near the sign-in pavilion were colorful close up.

We picked out hardhats (which seemed to be fall squash colors!) and flotation vests and gloves for our visit to the cave. The boats were loaded at the mouth of the cave; they held 4 people (including the guide). Our guide worked for a non-profit associated with water quality and was volunteering for this event. I appreciated his comments about the cave and its water quality (and the water quality of the region).

As we entered the cave, my husband took a picture of the mouth of the cave with the truck/trailer that brought in the boats.

The cave is not pristine in the sense that it was used as a fish hatchery in the 1920s and the mounds that were once mushroom beds are still visible. The water course has been cleared (probaby would not have been navigable by boats originally). Nubs of metal from old infrastructure are still visible. But the cave features are in great shape – still actively growing…unbroken…no algae growth. There are not any blind cave creatures; if there ever were any, they didn’t survive the fish hatchery days.

But there are bats. The ones in residence during our tour were tri-colored bats – roosting alone. They are very small….but stand out because they are often darker than the cave walls (the bat is to the right of center in the picture below). There is a colony of endangered gray bats that roost during their migration that number in the 1000s. We’ll go in September to see their nightly exodus from the cave!

This might be my favorite cave tour! I liked it because it was not as commercial. The only light was from headlamps. The tours happen infrequently enough that there isn’t algae or moss growing on the cave features (although there was fuzzy white mold growing on poop from racoons that wonder quite a way into the cave). Spotting tri-colored bats was a great challenge during the tour. The water flowing through the cave made for lots of drips….but also added to the ambience of being in a cave now being left alone most of the time.

Whooping Crane Boat Tour

/

We were at the dock for the 7 AM departure of our boat on the third day of the Whooping Crane Festival.

I took a few pictures before we boarded – the moon over the harbor area.

Our destination was the Aransas National Wildlife Refuge where Whooping Cranes feed in the marshy/shallow areas…only visible via boat and it took over an hour to get there from Port Aransas. We passed familiar areas early on and saw a group of American white pelicans, morning light with moon setting over the shore, roseate spoonbills and white ibis in the distance, and the Aransas Pass Lydia Ann Lighthouse.

Then we entered an area that was different than our previous tours and more open water…with occasional platforms with cormorants and great blue herons hunkered in the chilly morning wind. There was a tall bridge as well.

Then there started to be a lot of small islands full of birds: Cormorants, great blue herons and brown pelicans. One area seemed to have a lot of great blue herons and I wondered if the island was their roost.  There were also groups of laughing gulls. (Click on the small images to see a larger version.)

And then we started seeing Whooping Cranes. Even at a distance – they are easy to identify because they are so large…and so white. The young are rusty looking – particularly their heads. Many sightings were of 3 birds: 2 adult birds and a colt; it must have been a good year for increasing the whooping crane population!

There were other birds to see too between whooping crane sightings – roseate spoonbills, green-winged teals, willets, American avocets, more great blue herons, buffleheads, cormorants, an osprey, and reddish egret (that took off as a wave covered the spit of shells the bird was standing on).

I took some closeups of some shells…out of the water at low tide.

I also realized how wakes of boats impact the shoreline…why there are often blocks on the shore to reduce the erosion wakes can cause. It doesn’t take a big or fast-moving boat to cause damaging wakes in smaller channels.

And then we took a break as we headed back to Port Aransas – no more photos until the jetty with the usual brown pelicans.

We got back to the dock with plenty of time before our afternoon field trip for lunch; we then headed back to the Leonabelle Turnbull Birding Center.

Bird Photography Boat Tour

/

Our second day of the Whooping Crane Festival continued with another boat tour after returning from the King Ranch and a quick lunch. The afternoon emphasis was on bird photography. The difference was subtle. The guide did suggest some settings to accommodate photographing in the very bright environment of a sunny day. I opted to take the normal opportunities to photograph birds as usual…but then took some photographic challenges too.

I started before we even boarded the boat. Grackles were taking snack packaging out of a trash can. The female seemed to be unimpressed with her partner’s antics.

I attempted to get a double-crested cormorant taking off from the water…managed to capture the form and splashes of water but the eye doesn’t show….plenty of room for improvement.

There were terns (probably common terns) diving toward the water for fish. I tried pointing my camera in that direction and pressing the button to take multiple pictures in fast succession. It was hard to hold the camera still as the boat moved! The shape of the bird as it nears the surface of the water was something I couldn’t study until I looked at my pictures on a bigger screen. This was my first attempt at photographing feeding terns!

The back of a white-tailed hawk – the only sighting of this species of the trip. It isn’t a great picture in the traditional sense….but it does tell a story. The bird was sitting in dead mangroves; the mangroves died during very cold weather a few years ago and recovery is slow; hurricane damage to the Aransas area would be even worse than before if one comes through before the mangroves can become established again.

The birds always seemed to be a little further away than optimal…and the boat was rocking. But I took pictures anyway: white ibis, little blue heron, osprey, great egret, and great blue heron. I tend to take photographs rather than make notes about what I am seeing…it’s easier with the camera already in hand!

And then there were the reddish egrets… with their pink and black bill.

And finally one started foraging…moving rapidly in the shallows. It seemed to veer off suddenly…something there that the bird didn’t expect?

I took group pictures of birds on small islands in the water…always interesting to see how many I can identify on my big screen later. In the one below, I see brown pelicans (adult and juvenile), American white pelicans, cormorants (double crested probably)…all in the foreground.

As I zoomed in on birds that were not in a group I noticed a black skimmer and some Caspian terns.

It’s always a thrill to see a bird I would not have seen without being on a birding field trip like this red-breast merganser. It was a single bird…swimming rapidly away from the boat…and I probably would not have noticed it without someone pointing it out. I’m not sure it was the guide or another participant that noticed it.

The same was true for another black-crowned night heron.  I photographed one on the King Ranch in the morning! I was pleased that I was able to find and focus on the bird more easily than many of the others on the boat.

The light began to change as we neared the end of the day. There were enough clouds to try a non-bird landscape shot of the water the sky…a bit of land at the horizon.

I changed a setting on my camera to try an artsy image of a cormorant and the shore as we came back toward the dock.

And then the boat stopped just before we got to the dock….for dolphins. I couldn’t top my husband’s dolphin picture in the bow wave of the big ship, but it was fun trying to anticipate when they would surface!

And then one last picture before we got off the boat! It was a great second day at the Whooping Crane Festival. The next morning was an early one….getting on a boat at 6 AM to see Whooping Cranes in the Aransas National Wild Life Refuge. We headed to the hotel for an early evening to be ready for it.
