Research

The following project is being conducted  by Doctor Richard Banham, external Tutor for Leeds University,and bird ringer “experto” ,a member of MILVUS G.O.ES ringing group in S.W.Spain. This exciting project can be a great experience for university students especially from the fields of ecology, environmental science or biology to assist Dr.Banham, but it can also be suitable for everyone with strong passion for birds!

The program involves colour ringing of Passer domesticus in a semi-desert area at Urra Scientific Field Station near Sorbas and at an oasis called Los Molinos de Rio Aguas in the province of Almeria with the assistance of Sunseed. The project  started at the beginning of 2018 and was incorporated into the field study course for students from the ecology department at Leeds university from March 18^th till March 28th.,and continuing thereon.

Dr.Banham is conducting the program  throughout the year with a number of visits to Urra and Sunseed. Each year the project will be incorporated into the university field course,at Urra,always under his supervision.,and in future incorporating visits to the site at Los Molinos de Rio Aguas

Brief description about the project

This species has been chosen because it is the commonest local breeding bird in the area. The House Sparrow is very easy to recognise as there are no other common local species with which it could be confused.

For most of the year males have a grey crown and cheek area separated by chestnut brown eye stripe.The back is brown also but heavily streaked black.The bill is stout and blackish,with a black chin ,throat and upper breast.In winter period much of the black area on upper breast and throat disappears.

Females never possess the black  chin,throat and upper breast.The back colour is very much more subdued but is still streaked black.The cheeks are still grey ,there is no chestnut brown eye stripe and she has a broad light buff supercilium.Plumage remains the same throughtout the year.

Juveniles have the same plumage characteristics as females.

This species can be observed most commonly on the ground where they normally forage but can also occur on buildings and in the trees and surrounding vegetation.

Sufficient data will be collected by the participating Leeds University students to give them a viable project for the short time they have available at the field centre. However with the participation of Sunseed, much more valuable long term data can be amassed.

Methodology

When the birds are trapped they are fitted on the left leg with the normal metal ring on top of which is fitted a colour ring. Each year the colour of this ring is changed to note a new year.On the right leg is  fitted with 2 colour rings, one to denote the period of ringing and the other the age of the bird.All rings are fitted on the tarsus.

Color ring sequences on the right leg are different for Urra and Los Molinos so that the 2 sites can be distinguished

At Urra,and at Los Molinos it is noted at which net the birds are trapped (each net has a special habitat code), and then studied using binoculars or telescope in an attempt  to track the limit of each birds territory and to follow its foraging distance if outside the breeding territory. With a continuous colour ringing and observation program together with the trapping of controls, it will be possible to estimate the year on year survival rate of each sex of this species

It will be possible to track the birds outside of the Urra field station and Los Molinos itself as netting is also carried on along and beside the Rio Aguas rambla and in the future at another ringing site which will be set up in the rio at La Herrerdia.

In 2017, four water scrapes were constructed to try to attract both migrant/wintering and resident birds to drink. Mist nets were erected by these scrapes in order to trap and ring them. In March 2018 each scrape was observed by the students/volunteers to see if any of these colour-ringed birds came to drink and to note if this was outside their breeding or foraging territories.

At this moment in time these artificial scrapes are being replaced with more permanent materials as the pond liners used soon became very brittle in the Spanish sun and easily cracked losing all the water.

During the first ringing sessions in Spring 2017 with Leeds university students, the results showed that 52% of all the birds trapped were at these scrapes.

The colour rings for this project were available early February 2018. Having completed the first ringing session at Urra in February 2018, Dr.Banham visited Sunseed to provide all the necessary details for the project.

Importance of the project

The field station is in an extremely dry area of Almeria province and a further study is being carried out to plot the change in rainfall patterns since 1997. With less and less rain in this area, the presence of permanent small water scrapes could become more and more important to the survival of these local birds,and especially so in late spring through to early autumn when it can be extremely hot and dry. It is important to continue this project for a number of years in order to track any changes in the populations  of this species and to observe movements outside the boundaries of the station along the wide dry rambla of the Rio Aguas both towards Sorbas and in the other direction up to Los Molino de Rio Aguas and even beyond down the valley

A few kilometres down the river bed there is an important water source for the Rio Aguas in the form of an aquifer which results in a large permanent pool below  the village of Los Molinos de Rio Aguas. This natural water supply and the more lush vegetation, in the past has attracted a large number of birds ,some species of which do not appear at the field station.With permanent artificial water now available at Urra it will be interesting to see if there are any changes in the number and survival rates of local House Sparrows ,compared to Los Molinos.

It is quite likely with the presence of the permanent water body at Los Molinos that birds ringed at Urra field station will also visit this site to drink especially in the hot dry summer. It will provide interesting data as to how far local birds are prepared to travel to obtain water.

Post-juvenile dispersal may also reveal some interesting movements.

If the birds are found at Los Molinos other than at the lagoon, it again should be noted where and their activities e.g.feeding. This species is omnivorous so the population should survive during difficult periods.

N.B.The population dynamics for House Sparrows (e.g.increase or decrease of population totals year on year, numbers of breeding males and females,numbers of juveniles,survival rates) can be followed in relation to the variation in rainfall and the considerable increase in underground water extraction for growing new large olive tree plantations in the area.

How can you get involved in the project?

For those interested, all that is necessary for them to do, is to make a note of,the sequence of colour rings on both legs, the sex of the bird,the date and place of observation. Colour pictures and a field guide are provided to assist identification. A pair of simple binoculars is needed to observe the birds.

Please note that Dr.Banham has provided Sunseed with a bird identification guide to assist whoever is taking part in the color ringing program

Species information

This species has been chosen because it is the commonest resident scrub warbler in the area  and the birds perch quite prominently in the Spring as they are holding breeding territories. This warbler is very easy to recognise as there are no other local species with which it could be confused.

Both male and female possess long dark narrow tails with varying amounts of white or off white at the feather tips.Adult males have a jet black head a white chin and throat plus grey wings and back .Females also possess a white chin and throat,but have a grey head with a brown back.Both possess prominent red brown eye rings.

Juveniles look similar to females but possess a brown head.

Immature males have a mixture of brown and black on the head

Sufficient data will be collected by the participating Leeds University students during their Spring visit  to give them a viable project for the short time they have available at the field centre. However with participation of Sunseed, much more valuable long term data can be amassed.

If trapped feather samples of this part of the bird will be taken and sent for analysis to determine from which plant the pollen/nectar was taken..

Brief description about the project

These species have been chosen because they are the commonest wintering/migrant birds in the area of the field station, the surrounding areas towards Sorbas and in and around Los Molinos. The Blackcaps and Robins are very easy to recognise as there are no other common species with which they could be confused.

Adult Blackcap males have a black cap.The back is greyish and the wings are greyish olive with no striking visible markings.The tail is long with no white.The chin and throat are white.

Immature male Blackcaps sometimes have a mixture of brown and black on the crown. Females possess a red-brown crown.The back colour is more subdued than the male and the wing is more ochraceous with no striking visible markings. The tail chin and throat are as the male. N.B. Blackcaps only very rarely feed or are observed  on the ground.

The Robin too is easy to recognise with the bright red chin throat and breast.Males and females look exactly the same.They almost exclusively are seen and feed at ground level.

Sufficient data will be collected by the participating Leeds University students to give them a viable project for the short time they have available at the field centre. However,with the participation of Sunseed, much more valuable long term data can be amassed.
