Argentina

What on earth?! (13)

This tree in Corrientes prompted me to write this post. I knew it as a “Palo borracho” or drunken stick and I have seen them in Zimbabwe as well as in Latin America. I thought that all of them belonged to the same genus, Bombax. This is not so!

Bombax spp. are native of western Africa, the Indian subcontinent, Southeast Asia, and the subtropical regions of East Asia and northern Australia while the ones we get in South America belong to the Ceiba genus and they are native of the tropical and subtropical forsts of that continent..

Bombax ceiba, like other trees of the genus Bombax, is commonly known as cotton tree. More specifically, it is sometimes known as Malabar silk-cotton tree; red silk-cotton; red cotton tree; or ambiguously as silk-cotton or kapok. These trees have straight tall trunks and red  flowers with five petals that will produce a capsule which, when ripe, contains white fibres like cotton. Its trunk bears spikes to deter attacks by animals.

We have seen examples of what I now know are Ceiba spp. in Salta, Chaco, and Corrientes provinces of Argentina and they are rather special with their swollen trunks looking like bottles!

Above are pictures taken many years back of one of these trees that we found at the main square of Resistencia, the capital of Chaco Province.

Apart from “palo borracho”, the better known, Ceiba speciosa, is known as the floss silk tree in the USA is for “samu’ũ” (in Guarani), “paineira” (in Brazilian Portuguese), “toborochi” in Bolivia. It belongs to the same family as the baobab and the kapok.

Now that you are familiar with the “palo borracho”, perhaps it may be easy for you to spot the beast in the picture?

Lost…

I belong to a generation that did not lose telephones. The first ones I remember were known as crank phones (you needed to turn a handle to call the telephonist and tell her (I do not remember men doing this job!) the number you wished to talk to or, more recently, the dialling type. The arrival of the cell phone not only gradually made landlines obsolete but also placed phones, together with car and house keys and reading and sunglasses, among the losable items in our daily lives.

I do not like phones of any kind, and I admit not being very careful with cell phones misplacing mine quite often! Most of the time these are often only mild panics that disappear once the phone rings when called by Mabel and we reunite again.

The day before yesterday we went to Salta town in the morning. Mabel had a dentist appointment and I needed to get my hearing checked. After we completed our respective tasks, we met in town so that, together, we got some good (sugar-free) breakfast cereal. After that we drove to the shopping mall to get a few more things, including our laundry. The last stop was in Vaqueros, about 10km from our farm to get some of the great sausages that our butcher produces.

While waiting for Mabel to return with the susages, I noticed that my phone was not at its usual place in the car. As it has a tendency of falling from its place and hide under the seat I decided to search for it there, convinced that I would find it. When Mabel returned, I was undergoing a mild panic as the phone was not where I expected. A thorough inspection of the car and shopping bags produced no results. The same happened when we call my phone several times. Things were turning for the worse. The obvious conclusion was that I had left it in one of the shops we visited earlier or someone had taken it from my pocket while walking in town!

Before I go on with the story I need to clarify some technicalities. We have no cell phone network at the farm (being rather remote and surrounded by hills that interfere with the signal) but we do have a basic internet service that enables us the use of WhatsApp and Skype for phone calls. It is there where my MacBook resides from where I could look for my lost phone through the web.

Before we headed home, we decided to retrace our earlier movements in town and the shopping mall but we did not make any progress so, we drove to the farm to attempt to locate it from my computer. In its computers, tablets and phones, Apple places an app called “Find My” that is used when things like this happen. So, at the end of the afternoon we arrived at the farm and immediately “operation recovery” started!

After initial toothing problems I managed to get the app to work and found my phone. It was stationary at a shop in Salta town. I could see the shop (by using the street level view), but I failed to contact them by Skype to tell them that they had my phone. So, we decided to go back to Salta to visit the shop first thing in the morning.

After about an hour I looked again at the app´s map and, to my surprise, my phone was wandering through town! Spellbound, I saw it moving slowly for a while but then it gained momentum indicating that whoever had my phone walked for a while and then got either in a car or bus! I followed my cell phone journey for about an hour until it eventually stopped after nightfall. My phone had arrived to its new home! The fact that I knew where my phone was, made me somehow optimistic about recovering it.

The app indicated that my phone was “locked” and it offered me two options, to place a message so that the person could call me back or to apply the more drastic “erase” command. The latter would vaporize all my information from the phone if someone tried to unlock it. I chose the first option and placed a message, aware that we were not reachable at the farm, but hoping to get an SMS in Mabel´s phone when we were in town the next morning.

The news of the loss spread and friends and relatives recommended that I erase the phone and forget it as it would be impossible to recover it as the Police was unlikely to assist much. I took that into account but decided not to place the order to erase until the following day.

The morning brought a welcome heavy downpour as Salta had been going through a severe drought. However, the rain created an unexpected and serious drawback: the stream that we need to cross to leave the farm swelled and we could not cross it! That meant that we would not check for messages from the phone, increasing the risk, of someone breaking it. In view of this, I decided to place the “erase” command and, as recommended by friends, forget the phone and start planning for a replacement.

The day I lost my phone, and after my hearing exam I was recommended to start using a hearing aid on my right ear and this needed further tests to choose the right gadget. I tried to do this that same day but the place was busy so I could only do this three days later. I booked the appointment in the understanding that they would call me if there was a cancellation and they could see me earlier. While waiting for the stream to allow us to cross it, I decided to place a Skype call to them to see if an earlier appointment was possible.

I talked to the same receptionist I had seen who mentioned that she had called my cellphone several times to offer me an earlier appointment and that, eventually, a very concerned lady replied and informed her that she had found the phone on the street but could not contact its owner! Wisely the lady, called Eva, had left her cellphone number that the receptionist gave me.

From then on, it was all very easy! I called Eva and agreed to meet at a place in town where she returned my phone. I was very lucky!

Clearly, the world would be a great place if we would all be like Eva!

What on earth?! (1)

This was seen is the main road between the cities of Corrientes and Resistencia in Argentina. The cities are separated by the magnificent Paraná river and the road connecting the two is truly busy. It was while driving on the motorway that we spotted this oddity. We almost overlooked it but then we spotted something wrong. Can you see it?

It is not easy to see what is wrong! Here is another picture taken when the tractor got closer and with a different angle:

Usually, tractors move on four wheels! However, these gentlemen were driving -rather unconcerned- on three by some miracle of engineering equilibrium!

Spot the beast 81

Winter is not the best season to spot beasts at our farm in Salta, Argentina. Today was, however, an exception and we came across this beast that I would like you to spot and then I will give you more details about it.

To find the beast above is very difficult so I put a close-up to help you seeing it better:

I am quite sure that you have now find it. it is a Rococo toad (Rhinella schneideri) [1] that Mabel unearthed while shifting a pile of sand to build a carport at our farm. Luckily it was alive and unharmed but amazingly flaccid, clearly hibernating.

A cleaner toad for you to see better.
“Side B” of the toad.

This rococo had buried itself at the start of the winter, probably in mid May as the winter started early this year and it will resurface when the warmer temperatures arrive in September/October. We re-buried it as well as we could and marked the site so that we can watch it emerging when the first warm days arrive.

The following short videos give more details of the find and the condition of the toad.

These are the pictures of an active toad found in the back patio of our farmhouse earlier this year that I used to illustrate my earlier post on this animal (see [1]). Apart from its rather impressive size, I find its clear eyes truly amazing.

Suicide season

The Rufous-bellied thrush (Turdus rufiventris) is a songbird that occurs in most of eastern and southeast Brazil (where it is the national bird), Bolivia, Paraguay, Uruguay and central and northern Argentina. While in Uruguay they are known as “zorzales”, here in Salta they are called “Zorzales chalchaleros” or just “Chalchaleros”. While the English name for the species describes its distinctive reddish-orange underparts, the vernacular name in Salta reflects its preference for feeding on the fruits of a tree known as Chal-chal.

The Rufous-bellied thrush -very similar to the African Olive thrush (Turdus olivaceus)- occurs in different habitats (forests and urban treed areas) and it is common around rural houses where its song is one of the pleasures of rural living. An omnivorous bird that prefers arthropods and fruit it can eat broken maize during our dry winter season when food becomes scarce. As I mentioned earlier, one of its favourite fruits are produced by the Chal-chal (Allophylus edulis)[1].

We do have Chal-chal trees in the farm but not close to the house. However, about ten years back we planted a row of Hawthorn bushes (Crataegus spp.) to act as a wind-breaker against the predominant eastern winds that often blow in this latitude. This resulted in a rather unexpected high wall of trees that not only help to stop the wind but also yield what I estimate to be several hundred kilogrammes of red berries, towards the end of the summer months.

This plethora of fruits attracts a number of birds that include the large Dusky-legged guans (Penelope obscura), Chachalacas (Ortalis canicollis), Toco toucans (Ramphastos toco), Blue-and-yellow tanager (Rauenia bonariensis) and Sayaca tanager (Thraupis sayaca). Although the latter are rather spectacular, the most common birds that come to feed on the hawthorn are the Rufous-bellied thrushes. We probably have a few dozens of them constantly moving to and from the red berries.

Year after year, the resulting thrush heavy and uncontrolled air traffic causes casualties announced by loud bangs coming from our only large east-facing window in the house (that also faces the row of hawthorn trees about twenty metres away). Usually, about two or three thrushes (no other species do this) either die or get stunned after heating the glass. So far we have accepted this as an unavoidable consequence of the increased number of birds brought about by the abundance of food.

Sometimes the thrushes came at such speed that they broke through the mosquito screen as shown here by the Bolivian guiro (a musical instrument).

This year, however, the suicides (birdicides?) reached alarming levels and yesterday we had four hits (three dead and one recovered), a rather alarming number! Although the first bird that hit during early morning recovered, a second one crashed about an hour later so we decided to do something about it.

I remembered having read somewhere that if you drew lines on the glass with a highlight pen, somehow the birds eyesight would see them from far and avoid the window. I drew the lines and, satisfied with my job I called Mabel to see it. The moment we were close to the window a bird nearly hit Mabel’s head and the loud thud indicated another fatal outcome! The fluorescent lines did not work so, do not try this at home!

So, “encouraged” by Mabel I placed a rather obstrusive zig-zag of flourescent yellow tape that occupied the top of the glass, at the area the sky was reflected. We decided that it was better to interfere with our view rather than nhaving more casualties!

The yellow tapes in place.

So, proud with my work but now tired, I went for my obligatory siesta (a pleasure of these regions!) to recharge my batteries.

When one hour later I woke up, Mabel was very upset as a fourth bird had killed itself!

In desperation and after some more thinking, we remembered that we had bought some bird netting to protect our fruits. We placed the netting in front of the window in a way that resisted me throwing the Bolivian guiro that was the closest to a thrush I could find for a test!

The Bolivian guiro itself.

Below I show you the netting and a video showing how we expect it to work.

A lateral view of the netting.

We believe that the deaths will stop now but our discussion has turned now to resove the reason that compels the birds to do this.

A couple of years back we thought that the birds could see a mirror that we have in front of the window and tried to fly through. As the birds continued hitting the glass when we covered the mirror, this idea was abandoned.

However, we are convinced that the birds see the reflection of the sky in the window and try to fly through.

The presence of predators, in particular the Sharp-shinned hawk (Accipiter striatus) make us also believe that it could chase the thrushes and the latter, trying to escape, bump themselves against the window. In favour of this hypothesis is that we have seen the hawk catching thrushes and other smaller birds around us. However, it is unlikely that the hawk would try to kill four birds the same day when one would be sufficient for a few days.

That leaves us with the last hypothesis that had been put forward by Mabel: the ripe fruits of the hawthorn ferment in their crops and their small livers are not able to process the resulting alcohol with the result that they get drunk! The fact that the berries are ripe now and likely to ferment faster, supports this hypothesis. In addition, after “googling” the idea, I found that at least one similar event involving the hawthorn and Cedar waxwings (Bombycilla cedrorumhas) happened in the USA [2] and other instances of drunk birds also exist [3][4].

Our beast is a toad known around here as a “Rococo” and in English as a Schneider’s toad (Rhinella schneideri), a rather large toad known to occur from North and Central Argentina (including Salta, where we are), central Bolivia, the Atlantic coast of Brazil, Paraguay, and Uruguay in elevations up to 2,000 metres above sea level and in various habitats, including urban areas. They are often found around houses in rural areas.

The males can measure up to 17 cm in length and the females 25 cm. Their maximum weight can reach 2 kg! (the one in this post is probably 6-700g). It is a shy and mostly nocturnal beast that during the day relies on its colour and remaining flat and inmobile not to be detected by potential predators.

We often see this one at our small dam near the house but also it frequents our outside lights feeding on insects attracted to them.

Their call resembles a stake being hammered fast. The females deposit up to two thousand eggs in double strands deep in water pools and the rather large tadpoles hatch and feed on algae.

Despite its large size and excellent camouflage, rococos have some enemies, apart from men. The “Sapera” snake (Xenodon merremi) is one of its worst enemies but the toad can puff up with air to avoid being swallowed. It also secretes a bufotoxin that can cause vomiting, paralysis and even death in predators. We have observed a rococo attacked by a “caracara” (Polyborus pancus) that abandoned it when we approached them (I believe that the rococo only survived that beacuse of our fortuitous arrival).

In fact, I took the picture as an excuse to present you with this small mammal, the apereá (Cavia aperea) or Brazilian guinea pig.

As you can gather, it is a relative of the well known domestic variety, the guinea pig (Cavia porcellus) a more colourful and better known around the world. Its name is confusing as it is not related to pigs and it did not come from Guinea but from the region we are now: the Andes where they are an important and sought after food item.

The apereá is a diurnal and grass-eating mammal, pale grey-brown on its dorsal area and greyish-white ventrally. It is almost tailess with an adult length of about 25 to 30 cm and a top weight of about 600 g,

The apereá is found in Argentina, Brazil, Bolivia, Colombia, Ecuador, Guyana, Paraguay, Uruguay and Venezuela where it is a rather common mammal, often spotted on the roads, running away from cars, seeking shelter in their thick superficial grass burrows. They breed throughout the year and females can have up to five litters of one to five young each time.

Pirpintos

A short post to share with you a special situation that we have been going through at the farm for the last week or so. White butterflies that usually fly past on a migration somewhere they only know, have arrived. Unlike previous years, they have decided to stay.

Ascia monuste, the great southern white or pirpinto in Argentina is the only species in the genus Ascia. It is found from the United States to Argentina where they migrate yearly but only in one direction and without return. Despite their English name, they are rather small with a wingspan of 63 to 86 mm.

Pirpinto feeding on a Lantana flower.

Their main aim is to find plants of the Brassicaceae family (Cabbage, Kale, etc.) to lay their eggs for their larvae to feed on them. However, as there are several sub-species, they can also feed on other plants such as Lettuce, Alfalfa, Cotton, Rice, Potato, Chicory, Cassava, Passion Fruit, Corn, Mustard, Radish, Rocket and Soybeans to name a few.

The larvae will develop in 4 to 5 days and the adults will be appearing a fortnight later and they will feed on the nectar of plants such as saltwort, lantana and verbena while laying their eggs on some of the target species mentioned above.

We were enjoying their visit as they staged a great show that reminds us that Nature is able to create amazing sights.

Unfortunately, Mabel noted that the winged visitors had discovered her treasured rocket plants and they were busy laying their eggs on them so our focus has recently and urgently moved from contemplation to biological control to save our veggies!
