BirdSleuth Caribbean Lessons 4 & 5 – Habitat & Survivor

Habitat elements cover, cover, water, space,
and the bird in the pink dress.
I tried out BirdSleuth Lesson 4 Habitat in my Saturday morning UCI kids ecology program (2 hours, 15 kids, age 2 y.o. through 8th grade) and Lesson 5 Bird Survivor in the 7th grade UCC class (1/2 hr, 16 kids), and figured out what worked, and mostly what didn’t work.  In general, the kids in 6th grade and up weren’t so into the games.  And I realized that my translator and I really needed to demonstrate a round of both games with us as the birds.  Both games worked better when kids stay in their seats and the birds are in front.  Difficulties with habitat were that the kids wouldn’t continue to make the motion of their assigned habitat element (food, water, cover, space) throughout the game, and it didn’t work as a chase game as the birds and their habitat friends formed alliances, so there was not much chasing.  At the end I gave them markers and index cards to write the 4 habitat elements and draw pictures.  The older kids helped the younger ones, and they all seemed to enjoy that.


The Survivor game requires the kids to read cards describing the success of birds in 1. finding territory and 2. mates, 3. building nests and 4. sitting on them, 5. finding food, and 6. fledgings leaving the nest.  The birds standing up front take steps either forward or backwards depending on their success with each step.  First, a teacher wasn’t around and kids were trickling in from break, so they weren’t attentive.  Then I discovered my translator can’t read French very well!  So it was difficult directing the kids through the instructions.  Finally I went up front as the bird and asked kids to read their cards to me.  I understand French well enough to figure out whether to step forward or back.  Then finally the session was over.


I revised both games for the Saturday program in the Bohoc village (2 hrs, 25 kids age 2 – 15).  I wrote in Kreyol the 4 habitat elements and 6 survival components on laminated cards.  And as we explained each, kids came up front to hold the cards.  I assigned habitat elements to kids based on the color of their shirts so I could remember who was what (blue = water, etc.).  And my translator and I demonstrated collecting the 4 elements, making a competition of it to see who could gather all 4 first.  Then we had pairs of kids come up front as birds and race to see who could collect the elements.  For the survivor game, I distributed all cards to the kids, and my translator and I stood up front and in turn asked for the cards for each step in order.  Two older girls who could read French read the cards to us and we explained in Kreyol.  Both games worked much better with this group.  Afterwards the kids wrote the components on the index cards and drew pictures of birds.

BirdSleuth Caribbean Lessons 7 & 8

Birds Caribbean sent me materials written in French to lead a BirdSleuth Caribbean class for teachers in Haiti.  Before having a workshop for teachers, I am trying out the material on kids in area elementary schools.  The first lesson was a 1.5 hr Saturday morning program in two different rural villages with kids aged 2 to 15 years old.  I began with the poster of bird silhouettes to identify birds and discuss different groups. (I didn't follow all the  dialogue of the lesson or take kids out with binoculars).  From the first group I learned that the kids didn't know what a silhouette is (even though they speak French), so explained it to the second group as a shadow, and better explained that we don't need binoculars to identify birds, but can use their shape.  They understood this as the hummingbird has a long beak, the woodpecker is on the side of a tree, etc.  The kids didn't know the wading bird silhouette, and I have never seen any in this area.  We called it the kolye, the name for plover and killdeer. They also mentioned crow several times, but it is not on the poster.  They gave me the Haitian Creole names of the birds.  Then volunteers come up front and faced away from the poster to try to name all 10 types of birds on the poster.

Next we used the bird body part poster of Lesson 8.  Students gave me the Creole names of the parts, then I had volunteers come up front in pairs and the 'scientist' showed us the parts on their 'bird.'  We looked at the bird illustrations in the Haiti bird guide, and I asked the kids questions like what color is the eye stripe, or which bird has a black throat.

We then went into the surrounding and used the beginner side of the scavenger hunt cards (after emphasizing that they only use the dry erase markers on the cards).  They had played this came last year using the English language version and searching for only the illustrated items, so I thought with the French version at least the older kids would look for more items since some are described only with text.  But in both groups all the kids stuck to looking for only the illustrated items.  So when I have lessons with only the older kids I will emphasize the written items.  Stay posted for the results of future lessons.

Many Hands for Haiti ecology seminar

Thank you Many Hands for Haiti for inviting Louiders and me to your campus to give an ecology lesson to the agronomy students!  We hope the students better appreciate how protecting Haiti's ecology protects the lives of people and livestock.

Our 2-hour lesson focused on watersheds - how what we do impacts those who live downstream of us.  If we plant more trees and protect the rivers and lakes, we will have more fish and cleaner water.  Washing people and vehicles and watering animals away from the river helps everyone.  We finished with a lesson on microbes in water and everyone received a kit to test for E. coli in their drinking water.  If you find E. coli in your water it is a sign of fecal contamination!  Which means diseases such as cholera could be present.  After we finished someone showed up with two bouanma fish (carp) from the Bouyara River!

Well Survey – Bohoc Haiti

Protected Lejene well.
On 17 Jan. 2017 I performed a brief survey of 4 pump wells in the Bohoc area (8 miles east of Pignon), three along National Route 3 and one in the village of Caiman.  I collected water samples to measure nitrate with a LaMotte® Water TesTab® Kit which measures nitrate-NO3 in discrete categories (0, 5, 20, 40 mg/l) determined by color change.  I used 3M petrifilm to determine presence of fecal coliform (blue colonies are E. coli, red colonies with gas are other coliform).  Coordinates were taken with a handheld GPS.

Two of the wells were in protected blue and white buildings that are kept locked and managed by a well committee.  At both wells people drink the water without treating it, and also use it for washing and cooking.  One committee said they treat the well once a month with chlorine, and that people must take off their shoes before entering the building.  People at the Caiman well said they do not drink the water, but use it for cooking and washing.  At a second unprotected well, someone said that some people drink the well water but shouldn’t. 

Caiman well.
Surprisingly none of the wells showed E. coli, nor even other types of coliform, indicating that here is no contamination from fecal material.  Of concern is nitrate levels.  High nitrate in drinking water can cause methemoglobinemia (blue baby syndrome) in babies less than 6 months old as the nitrate depletes oxygen in the blood.  The USEPA maximum standard for nitrate-N in drinking water is 10 mg/l.  The WHO maximum standard for nitrate-NO3 in drinking water is 50 mg/l (or 11.3 mg/l nitrate-N).  Nitrate-NO3 values were multiplied by 0.2259 to convert to nitrate-N.  The two protected wells were below the nitrate limits, however the two unprotected wells had at least 9.04 mg/l nitrate-N (40 mg/l nitrate NO3), the maximum value that the LaMotte kit can report.  Therefore water from the two unprotected wells should not be given to babies < 6 months old until further tests can determine actual nitrate levels.

The results of this study were shared with the well committee and users, with cautions to those at the unprotected wells to avoid giving this water to babies.
