The original Java sparrow birdroom diary is back! This page will detail all the highs and lows direct from the birdroom, all the information on now my Javas are doing generally and at the more interesting times like when I am letting the pairs go down to breed. Please select a month below to allow you to read about the diary of events in that period.
The differences in the business of nest building are clearly seen in the images above but this does not mean that the pair that do not appear to be nesting much will lay their eggs last. It may be that they like the coconut fibre lining to their nest rather than using shredded paper. I am confident that all pairs have been in the nestboxes so this in its self is a good sign, and also all pairs seem to be getting on well with both sexes in each cage perching close to one another and no squabbling being witnessed to date. January 4 January 5
I have also got the first egg in a Gladwin & Drury pairing in another breeding cage, it is nice to see the eggs begin to appear again, it has been a while! January 6
January 13 Please roll place your mouse over the image below to see the situation in the nest when I first looked in today and then the second image will show you the better looking clutch with nothing obstructing the eggs and thus possibly stopping the eggs being correctly incubated. I do have concerns about the state of the nest of another pair of my Normals, it is rather flat and elongated and this could mean that eggs could get rolled into corners of the nest and not be incubated and eventually hatch. You will also see in the photo below that the eggs are not in the nice round arrangement when you have a pair that has a nice, reasonably deep nest bowl.
The last nest I checked today that has its first egg laid is also one I have got to watch as the other eggs appear as you can see by the image shown below, once again daily checks will ensure the clutch if fertile, will hatch normally.
January 13
This cock bird was "paired" to another Java and not surprisingly their pairing produced no eggs at all! So, I have now put in the spare Stuart Drury hen I have in with the 100% known cock to see what happens, eggs in 2 weeks I hope! I have moved the 26 x 2007 bred Javas I still have here into 2 groups of 13 and also out in the cock above in with one group. The 18 late bred Javas were in lower, poorly light cages and I feel this along with the winter conditions is stalling the birds moult into adult plumage. I have uploaded a couple of shots the the 2 groups of Javas below.
January 21 I have got my 2008 close rings from A C Hughes as well and I am looking to use all of them, I ordered 60 and would not be too disappointed if I had to order some more, the 60 close rings can be seen below. Oh yes and they are in my favourite colour too!
January 21
There are 5 active nests at the moment with 4 having a total of 27 fertile eggs in, so a promising start to the 2008 breeding season. January 26
As soon as I get chicks in the nests I hang the closed rings that will be fitted onto the nestbox, numerically as they hatch they are placed on an old storage pin and hung on the nestbox as a reminder that I have to ring young in the days to come. I also write the ringing date, 10 days from hatching on the nestbox sheet along side the number of the close ring to be put on the bird when it is big enough to accept it without it falling off!
I also mentioned back in my January 13 post I was concerned about the flatness of the nest with a certain pair of Normals. Well I have now tried to address this worry now a chick is in the nest (#2 Java above) and I have as you can see below placed some nesting materials to increase the 'bowl' effect in the nest to try to stop any chicks being dragged out of the nest. I will of course be checking this nest on a regular basis from now on and will keep you posted to see if my nest rebuilding has worked.
January 28
January 30
Please see a couple of images below that you have to time well to be able to take, well more luck than good timing really, the actual time a chick hatches or begins to at least.
February 6 Below you can see a fertile Java egg from the nest mentioned above. Clearly you can see forming veins coming from the mass which is actually the Java developing. If you get the chance to look at your own fertile eggs at this early stage you will be able to see the heart beating, it will look like a very small pulsating dot and no more, a quiet incredible thing to see really.
The last pairing a Stuart Drury cock to a 2007 bred Nesbitt hen now looks like eggs will follow soon as the young bird I bred last year (#10) has now got a very swollen vent area indicating an egg is in place for impending delivery, again we will see. When you have Java chicks in the nest you will notice more urgency at feeding times from the parents and I see on a daily basis the parent Javas diving down to the softfood and seed when it is replenished and in some cases I do not get my hand out of the cage before the Javas are sampling the fresh food. Below is a photo of such a bird that at times like this, a nest full of chicks it seems to lose any fears and its main priority is to feed its hungry young birds.
I have also today begin to place the first close rings of 2008 on a few young Javas that are big enough to ensure the rings will not come off again when they are put back into their nests. I rang a total of 5 young and will be checking on a daily basis all young in the nests for either the need to fit a ring or to check that one I put on the day before is still on the Javas leg. February 7
Today I managed to get a photo of a Normal cock that refused to leave his young and to test his resolve I left the lid of the nestbox in the open position while I got my digital camera to take a pic, he never budged! See below, I had to move him off the young with a finger. it took several times before he relented and let me check his family.
February 10 I have been altering my birdroom round a little too. The end of my birdroom which held some breeding cages and storage cupboards has been totally revamped to accommodate a small colony of Timor Sparrows I have, 6 have been placed in the 6 foot x 3 foot inner flight. Nestboxes will go up soon to see if they will breed in this arrangement, sadly cages has not worked. A couple of images can be seen below, one shows the flight from the birdroom doorway and the other the fittest and best looking Timor I have in the colony, it is a cock bird.
February 13
I thought it would be a good idea to show how I judge whether or not the close ring fitted to my Javas will stay on the bird. Once the ring has been fitted (go to my close ringing page) I slowly and gently bring the ring back over the ankle joint of the Java to see if it passes right off the foot or not. The rollover image below will I hope show you the difference in a bird that is OK and one that will need to be checked tomorrow to see if it has grown sufficiently to accept the 2008 close ring and that it will not fall off in the nest ands potentially get lost for good.
February 18
February 19
Now I do not know why the chick was unable to get out of the egg but maybe it unfortunately died trying and the parents knew this and decided to remove it from the nest. Anyway it is a sad bit of news but sometimes happens in both nature and aviculture alike. February 22 As expected the only pair of Javas I have on eggs now are sitting on 7 infertile eggs, so I am going to remove the eggs and split the pair up for a week or so. I will then decide what to do from there. All other young Javas are doing well and with all the eggs in the nest mentioned on February 19 doing well, with only the single causality shown above. This give me a total of 33 young in the 5 nests and with this I am pretty content.
The birdroom is now filling with the sound of young fledgling Javas, a total of 20 from 3 nests are checking out their quarters. The nest with the later hatched young in are doing well with 2 of the 7 being close rung now and hopefully the rest will be rung successfully over the next couple of days. Please see 2 photo's below of some of the newly fledged young and one showing the progress of the 7 later to hatch Javas.
March 6 Last night March 5th, I gave my second Java sparrow talk of the year to the friendly folks of Kettering & District Cage Bird Society and again I hope I opened a few peoples eyes to the wonderful Java and some of its history and future too, thanks to Steve and all for a great night! March 17 The first 20 young Javas have been placed in the large flight I have along with as usual, an adult hen to ensure the babies are soon to learn where the food and water is located in the birds new housing.
You can see from the photos below that once a pair of Javas has just about weaned their current round of young the next set of eggs appear quiet quickly and this is good in one way but problematic in others, areas like:
The new pair of Normals I put down at the end of February now have begun to lay their first clutch, I bought a pair of Javas from Newark sometime ago but sadly when I got the pair home I saw the cock had 2 toes missing, this was not seen when I bought the birds in the hall as it was always on the floor and its feet were buried in the deep seed covering the bottom of the cage, I should have known better!! The 2 images below illustrate nicely the differences to look out for if your hen in a breeding pair is about to lay her eggs. Look at the vent areas in the 2 photos below and you can clearly see the swollen vent of the hen, in fact she laid her first egg for me the day after this image was taken on the 15th of March I think!
March 23 Good news in 2 other nests (see 2 photographs below), both have had young birds hatch, only 1 in each nest but that is ok, I do not think I will get more than 3 in each of these 2 nests due to the fact the eggs we laid while the pairs had young still in the nest and as the pair above where all the eggs were removed, the full clutch was not incubated in the right manner.
The only nest with feathered young in today had all 7 Javas fledge, I noted today's date on my calendar and will remove the babies in 14 days time now I have seen all the young birds out of the nest. I would also expect to see eggs follow soon from the hen in this pair. Check out the picture below showing all the young with the parents and if you click this image a larger one will open focusing on 3 of the 7 young nicely posing on a perch.
March 26 The other pair on 6 eggs sadly will soon have their eggs removed due to them not showing any signs of fertility. This is the second hen the cock in this current pairing has ben put with and so far I have got no resulting young so it may be down to him for some reason not mating correctly or indeed at all. I do have a spare cock bird to put with the hen but he obviously is not in top breeding condition so when I decide to split the pair in a few days I will possibly put both birds in the outer flight cages for a rest. March 29
I am sorry if you have tried to access my site over the last 2 days and not been able to get on it, this was due to some technical issue. Do not ask me what but all is ok now. I am going to the Java sparrow society AGM tomorrow in Worcester and am looking forward to meeting Java pals both old and new at the meeting. I have removed the 6 clear eggs and split the pair up as I said I was going to do. I am unsure if I will put them down again as a pair, I will decide in a couple of weeks but in the meantime I have taken out the divider from this no vacant cage and the one next to it that is holding 7 young newly fledged Javas to give them more room while I have this option available. Being able to do this is a good example why dividers between your cages are in my mind, a very good idea because of the flexibility they can give you at times like this one, please see photo taken today of the family of Javas enjoying more space before the young birds are taken from their parents next weekend. Already the hen has begun to lay her next round of eggs with egg number 1 coming today.
I am also saving all the discarded, infertile and fertile eggs from 2008 to see how many are typically thrown away in a Java breeders birdroom in a season. The image below shows the amount I have saved so far with the 6 clean but sadly infertile eggs being at the bottom of the dish.
The 2 nests mentioned on my March 29 posting have got 7 healthy young in and the last pair on their second round who's eggs were due to hatch around this date have produced 4 young so far, maybe 3 more to follow. So I am really pleased with this and these young appearing yesterday from this Drury x Pover pairing, can be seen in the photograph below, these 4 young take the number of Javas hatched so far in 2008 being 44.
April 7
April 12 You can see from the 2 photographs below how dirty and dusty the job can be when cleaning out, as if you didn't know already eh? The 4 flight cages I have do have quiet deep litter in them, I use say around 30mm minimum of EasiBed but when left for a while this can easily double in depth due to wasted food etc. and in the image below left you can see just how big a pile of dirty cage litter you can have at cleaning out time, surprising eh? Also shown below right is a rather scary photograph of yours truly showing the precautions I take while I am cleaning out my birds, I wear a mask, sorry but I know its a bit worrying to look like this (some say I look better like this!) but it is a vital piece of kit in the birdroom to stop getting harmful dust and germs into your chest and airways.
The 2007 bred Javas are slowly, very slowly getting their adult feathering and I have now as I said placed them back into the cleaned flight cages in what I think are cock and hen only arrangements.
I have got a couple of Java friends waiting to take up to 6 pairs once they have fully moulted but the birds have got different ideas and are taking their time in doing so, but there is not a lot I can do but wait, I reckon by the end of May they should all be about ready, which would be a moulting out period of around 8 months. April 13 I look at the length of the growing feather quills on the birds wings too, usually at around 10 days of age you get a quill growth on the wing of about 3 to 5 millimeters and this is a pretty good guide the young Java is nearing the time when the closed ring will stay on. See the image taken today of the quill growth of a Java that successfully had its ring fitted with no chance of it coming off, a perfect fit! If you click this photograph then another, larger image will open up showing the difference in oldest and youngest birds in a clutch as mentioned above. The 2 Javas in the larger image are 3 days different in age.
Obviously what I am detailing today does not mean it is always the same for every clutch of Javas but is more of a guide on how I work in my birdroom for you then to look at how things go for you and your Javas to then let you develop your own methods in managing your livestock.
April 19
April 23
The youngest Javas I have currently in the birdroom are growing well, now 3 to 4 days old, image of the small clutch below.
April 30
I have had to do a lot of nestbox 'housework' over the last few days too and as you can see from the 2 images below it is vital to check your next clutch of eggs are in a nice deep and clean nest bowl to try to ensure they do not get dragged out by earlier round young that may still be in the nest or an over sensitive pair that shoot from the nest as soon as you enter the birdroom.
Out of these 9 eggs there are 4 to 5 eggs showing signs of fertility and this will the last round of young from this pair, certainly over the summer months anyway. I do have a concern that this nest will only have one or two young hatch out as I think the fact the earlier round of Javas has meant the parents were unable incubate as they would have liked, this could due to caring for their earlier bred young, but we will see (this is becoming a catchphrase for me in 2008 I think!). I took 4 young Java from a pair over the weekend and noticed 3 of the 4 young have lost their tails for some reason, initially I had thought only 2 were like this but the tail on the 4th young Java was not in a brilliant state either. I am not sure why this is the case, I have had it occasionally happen in the past but not with so many young in one nest. Please see images below, you will notice that on the photograph below right the new feathers are growing already and that they are the beginning of the classic black tail of the Java when it is in adult plumage.
May 21 If you have a local club or society that I may be able to travel to in one night and you think they would like to take the weird and wonderful journey through the history and more of the Java sparrow then please do e-mail me via the links on this website. The season in regard to breeding has gone well with a total of 53 young either fledged or in the nest, this is not counting the fertile eggs in other nest too, so more may come yet before I begin to wind down the Javas breeding season for a well deserved rest over the summer months of July and August and also into September. I have had a lot of clear eggs and clutches that were removed due them being laid to early (when previous round young were still in the nest) and not incubated correctly for the same reason I feel. I have also had a first in all the years I have kept Javas, this I will recount in both words and photographs below. The pair in question is my oldest one with the Nesbitt 2003 bred cock being with a Phil Thompson 2004 hen bird. They have reared 2 clutches, I think 9 young in total and during the rearing of the second round the hen began to lay round number 3, not unusual at all in my birdroom so nothing concerned me at all here. The hen typically lays largish clutches of 8 and 9 and true to form 9 eggs finally appeared and incubation of sorts started, of sorts because for some reason the hen got in her mind to keep covering the eggs with shredded paper and thus the eggs at the bottom were not being heated correctly by the hen as she was not in direct contact with them as you would expect. Anyway the hen carried on this burying process she had decided to embark on and when I could I removed the paper to reveal the eggs again, eventually I decided to make a paper 'bowl' from some kitchen towel and placed all 9 eggs in this to see what happened, yes you have probably guessed it, the same again and almost immediately too! I thought ok I will see what happens the next day and then make my decision to either remove the eggs totally or not. I saw on the next day then hen had laid another egg on top of the hidden clutch. She is now on 4 eggs and I have not bothered yet to remove the eggs from under all the paper under the new clutch. Please see 3 photographs below of the egg sandwich story!
I then noticed then that the cock bird appeared to be a little bald under the chin, it would seem like the hen as been over zealous in the preening stakes and as you can clearly see from the image below no trace of feathers at all, the total area of black feathers usually seen under the chin of Normal Javas is no gone!
So quite an interesting time and we will see what happens with these eggs that follow. Have you experienced this kind of thing before with your Javas? If so please e-mail me to let me know by e-mail. The earlier bred young Javas are doing well and moulting out nicely and oddly enough they are coming into adult colour quicker than the 16 or so late 2007 bred ones! Another oddity that I cannot really put my finger on as to why it is happening, perhaps you can let me know too!
The 2 nest with young in I have at the moment are doing well with 3 now fledged and in around 10 days they should be ok to move from their parents and a nest of newly hatched young are doing good too with the 4 Java babies being cared for in true Java sparrow fashion, see image below of chicks #50 to #53
The birds above if they all survive will bring me to a total of 66 young bred so far in 2008 with 64 being from 5 pairs. I am pleased with the way the birds have bred overall and still could get another 3 chicks from the nest with only 2 hatched out in so far, we will see. Due to the fact I am winding down the breeding for a while I guess that the regular diary entries may slow down, but I soon hope to show you some of the young bred in 2008 that are now colouring up into their adult plumage nicely My Java news from July to December will continue on another page ~ link to come |
