Gulf Coast Swallow-wort a variety of milkweed along Rettilon Rd

Walking Rettilon Rd

The litter walk at dawn I love it! Yup I'm a little nuts. Forth of July is coming and with it beach goers. We like to pick up the litter before the holiday because if people see a trashy road they will add more trash. I probably wouldn't ever think of just a lazy walk down Rettilon Rd at dawn in late June but picking up litter gets me there and this morning it was gorgeous. All the grasses are blooming. I am constantly amazed at how resilient coastal plants are. After a horrendous storm there they are growing through the salt crust, not seeming to mind that is hasn't rained in months.

I was surprised to find lots of the little milkweed vine blooming. I never noticed them there before. We have found many Monarch caterpillars on it in Mundy Marsh but there were no caterpillars around today. There were Clapper Rails - one brave or dumb full-grown chick watched as I picked up cans. I wondered if he had ever seen a human before. A pair of arguing Scissor-tailed Flycatchers sat on the fence and Eastern Kingbirds flew by. I heard Common Yellowthroats calling from the old dump, a good place for birds but not for people.[More]

Bolivar Flats Changes
by Winnie Burkett
6/26/09

Bolivar Flats has always been a very dynamic place. The beach grows, the marsh grows, the marsh dies, the beach is rearranged. There has been some moaning and groaning about it lately and I want to set the facts straight. Yes, Bolivar Flats is different. The beach adjacent to the gulf was reconfigured, sand and sediments pushed back. It made some real neat high sandy habitat which the Least Terns love. It killed a lot of marsh, and Willets are nesting there now. It raised marsh edges, and more marsh is growing in the areas where it is now shallower. Much of the sand was pushed over to the jetty forming what I call the jetty bar. Lots of birds roost there - there were hundreds of birds there this morning. These birds are seldom disturbed, many are probably the same birds that once sat at the end of the beach, which used to be the high spot at high tide. They were disturbed there frequently. The jetty bar is a better place for them to be. The Bolivar Flats and mud flats adjacent to the jetty have not changed much. Thousands of shorebirds spent the winter there finding lots to eat.[More]
 


Bolivar Flats Least Terns
by Winnie Burkett
6/26/09

I spent 3 hours at Bolivar Flats this morning putting signs around the Least Terns and looking at what is happening there.

I was there because I had been contacted recently and told that there were no signs around the Least Terns which apparently was why photographers wound up too close to them. We hadn't put up many signs because the terns are away from the beach and we didn't think there would be any disturbance there. I have always felt that most of the disturbance was caused by fishermen and beach goers who hadn't been educated about the impact of disturbance of beach nesting birds. Obviously the fishermen and the beach goers aren't the only people who haven't gotten enough education.

Disturbance of beach nesting birds can result in the death of the chicks in the following ways.

  1. Heat can kill chicks and eggs. If the adults are trying to scare away intruders they are not shading the eggs and chicks and the chicks can die in 5 minutes or less.
  2. Predators can grab chicks and eggs when the adults are off the nest. If the adults are trying to chase you away the eggs and chicks can be picked up by Laughing Gulls and Gull-billed Terns who hang around Least Tern colonies and grab chicks whenever possible.
  3. Human scent near a nest leads mammalian predators to the nests. Skunks, raccoons and coyotes know that by following human scents they can find food, sometimes it is trash and sometimes it is nests. If you walk up to nests you are leading predators there.

So PLEASE LEAVE NESTING BIRDS ALONE!!!

There are 40+ pairs of Least Terns sitting on nests at Bolivar Flats.[More]
 


Wood Storks at the Rookery
By Andrew Beck
6/19/09 12:12 PM

Susan Knock from Texas A&M in Galveston posted on TexBirds on Thursday that Andrew McGinnes observed Wood Storks at the Rookery at Smith Oaks. Today I was fortunate enough to walk up to the observation platform and snap a shot just as what seemed like every bird out there flushed. If you look around, you'll see the Wood Storks. The pond is so low that more and more land is being exposed everyday. This being the only fresh water around, the birds are here in numbers. Come down and see the juvenile White Ibis, Black-bellied Whistling Ducks, juvenile Snowy Egrets, Roseate Spoonbills, and so many others.

Saum's Prairie Lives On
By Andrew Beck

I stopped by Brays Bayou Pocket Prairie today to install a sign so passer-bys can know this rescue prairie by name. Don Verser met me out there and provided water for the concrete to set up. I was amazed to see how well all of the grasses from Saum's Prairie, now Greenhouse Rd., are thriving. It is truly a prairie pocket, and after seeing the plant and insect diversity in this 600ft2 plot, I only wish the banks of Brays Bayou could be as wildly diverse.

Counting Evia Island

6/11/09

May 28, 2009 Andrew Beck, Jason Perry and I went to Evia Island with Audubon Warden Bob Gallaway and his volunteer Bob Horner. Our goal was to count the birds nesting on the island and look at what needs to be done to the island to restore nesting habitat. Evia is on the back side of the Bolivar Peninsula and was built with dredged material from the widening and deepening of the Houston Ship Chanel. We had not been to the island since Ike but had seen pictures of the island. We knew that most of the vegetation was washed off the island, the rock rip rap was moved and the island was covered with debris. We were not prepared for the birds response to the changes.

They were nesting everywhere!! Herons in cavities in the rocks and in TV's. Their determination to nest on the island shows how important that location is to them.

Marker 52 Island

Counting West Bay Islands

6/10/09

May 21, 2009 Andrew Beck, Jason Perry and I went out in West Galveston Bay with Audubon Warden Bob Gallaway and his volunteer Bob Horner. Most of the Islands were full of birds despite the hurricane and drought. Brown Pelicans from North Deer Island "spilled over" on to Marker 52 island a couple of years ago. The White Ibis used to nest on North Deer but moved to South Deer which is a very low island, several years ago, maybe there just wasn't enough room on North Deer any more.
